It seems that every culture has it’s morning jump-start beverage— coffee, origination in Africa; tea from China; yerba maté imbibed in temperate South America, and chocolate which 500 years ago radiated out to the world from Central America. These plants contain caffeine and chemically-related stimulating alkaloids. Depending on preparation methods, all have their own variations on healthful antioxidants. Europeans adopted these beverages with further refinements.
But what happened to North America’s—yaupon holly? Like other morning beverages, yaupon is loaded with antioxidants, and is the only plant from North America that contains caffeine. Like yerba maté, it is a member of the genus Ilex (hollies). You can buy evergreen, red-fruited yaupon hollies at almost every nursery in the South. Common in forests of south Arkansas, it evolved in the Ouachita Mountains, then spread throughout the Southeast.
If you were a pre-revolutionary European explorer entering a native village along the Gulf Coast, elders would greet you with an offering of yaupon holly tea. Native groups cultivated yaupon in naturalized groves beyond the plant’s natural range. The leaves were carefully plucked, dried, then prepared and offered as a sacred ceremonial beverage. Referred to as “black drink” simmered to a thick brew (think “espresso”) it was called “cassine” or “asi.”
English naturalist, Mark Catesby (1682-1749) author of The Natural History of Carolina, Florida and the Bahama Islands published from 1731-1742, describes a cleansing ritual in which on one day a year, all of a tribe’s members drank black tea to induce “spring cleaning” (vomiting). Yet, the other 364 days of the year, an infusion of yaupon leaves was drunk like we drink coffee or tea in the morning.
Today yaupon is making a come back. Now you can do an internet search for “asi tea” or “yaupon tea” and instead of references to historic literature, you will discover several small companies offering teas and beverages from the yaupon holly from Texas to Georgia.
Well-established as a beverage tea after the American Revolution, the Civil War seems to have disrupted sourcing in the South and relegated the plant’s use to history until now. Confused botanical nomenclature, finally clarified in 1949, may also have impacted perceptions about the plant. Since 1949, the accepted scientific name, bestowed on the plant in a work by English botanist William Aiton in 1789, lives in infamy— Ilex vomitoria.
The American Botanical Council’s flagship magazine noted internationally for quality, reliability, and beauty in reporting on medicinal plants
AUSTIN, Texas (August 8, 2018) — August 2018 marks the 35th anniversary of HerbalGram, the quarterly journal of the American Botanical Council (ABC). Since its first issue in 1983, HerbalGram has transformed from a black-and-white newsletter to a full-color, 82-page journal with the visual appeal of beautiful botanical photography and intellectual draw of peer-reviewed articles. Though HerbalGram has evolved significantly, its editorial mission to serve as a reliable herbal education resource has remained the same.
In the summer of 1983, ABC Founder and Executive Director Mark Blumenthal produced the first issue of HerbalGram, which was then titled “Herb News” with the subtitle “Herbalgram.” Blumenthal, who also was running his former herb distribution business, Sweethardt Herbs, spent many of his nights and weekends collecting, writing, and editing articles for the newsletter. It was this focus on disseminating trustworthy and timely herbal information that would eventually lead Blumenthal to found ABC in 1988.
Originally published with financial support from the newly formed American Herbal Products Association (AHPA), of which Blumenthal was a founding board member, the first HerbalGram was an eight-page, black-and-white newsletter stapled at the spine. It consisted of “herb blurbs” on herbal miscellanea, a “media watch” section with herb-related news articles, a handful of paragraph-long “Rob’s Research Reviews” authored by then-Associate Editor Robert McCaleb (who, at the time, was also head of research at Celestial Seasonings), listings of herbal information resources and schools, and more. The editorial staff included just Blumenthal and McCaleb, who also co-founded the Herb Research Foundation (HRF) together.
For the second issue, Blumenthal enlisted two additional part-time assistant editors. The publication now featured the title “Herbalgram” in larger font. This issue took on a more defined format, with organized sections on industry news, conferences/meetings, HRF news, and “potpourri” — a catch-all section featuring various news items of possible interest to the growing herbal industry and community.
In the following years, HerbalGram transformed into a modern force in the botanical medicine community. In 1988, HerbalGram issue 18/19 was the first color edition with a cover illustration of St. John’s wort (Hypericum perforatum, Hypericaceae). This 48-page double issue also was the first published under the auspices of both HRF and ABC, which Blumenthal founded with the late ethnobotanist James A. Duke, PhD, and the late Professor Norman Farnsworth, PhD, in order to help transition the publication from newsletter to journal. In 1992, issue 28 was the first full-glossy, four-color issue, and featured an image of the Ware Collection of Blaschka Glass Models of Plants from the Harvard Museum of Natural History on the cover. The journal increased to its current length of 82 pages in 1999, and, in 2000, issue 50 was the first to be published by ABC alone.
Eighteen years and almost 70 issues later, the editorial staff of HerbalGram has grown to include an art director and three full-time editors, in addition to Blumenthal, who serves as editor-in-chief, along with many other employees at ABC who serve in a variety of other important roles. The journal features articles both from in-house writers and botanical experts from around the world, and all are peer-reviewed by members of ABC’s distinguished advisory board or other professionals with relevant expertise. HerbalGramreaches thousands of readers in more than 81 countries who represent a range of diverse professions, from research scientists (e.g., pharmacognosists, ethnobotanists, etc.) and health practitioners (e.g., herbalists, naturopathic physicians, pharmacists, conventional physicians, etc.) to industry members, government regulators, and many others.
HerbalGram has been a leader in presenting extensive literature reviews on specific herbs in an effort to help establish a scientific basis for their potential health benefits. In some cases, these reviews can also help clarify erroneous or inappropriate claims about the uses of the herbs.
“HerbalGram has served as the go-to source for detailed perspectives on developing herb-related topics for 35 years,” said Steven Foster, an herbalist, photographer, author, and ABC Board of Trustees member. “The publication is at the forefront of covering topics such as herb conservation and the effect of climate change on herb crops, clear assessments of regulatory and market developments, as well as emerging science.”
Foster added: “The depth of coverage, detailed quality of presentation, rigorous peer-review process, meticulous editorial attention, aesthetic beauty, and broad appeal [of HerbalGram] combine to reach a standard of lasting excellence that few science-based periodicals achieve.”
Loren Israelsen, president of the United Natural Products Alliance, praised HerbalGram’s diverse content. “When my HerbalGram arrives in the mail, I know I will begin another journey into the wonders of the herbal kingdom,” he said. “While I no longer save other magazines, I treasure and hold tight to my copies of HerbalGram. I, along with many others, salute ABC and HerbalGram for its 35 years of service to the advancement of consumer, industry, and professional education, high level of professionalism, and documenting the rich history of our remarkable community.”
In November 2011, the ABC-AHP-NCNPR Botanical Adulterants Prevention Program (BAPP) published its first feature-length article — “A Brief History of Adulteration of Herbs, Spices, and Botanical Drugs” — in HerbalGram issue 92. The article, written by Foster, reviewed numerous cases of adulterated, fraudulent foods, spices, and drugs during the past two millennia. HerbalGram also has published extensively peer-reviewed BAPP feature articles on the adulteration of bilberry (Vaccinium myrtillus, Ericaceae) extract, skullcap (Scutellaria lateriflora, Lamiaceae) herb, so-called “grapefruit seed extract,” and black cohosh (Actaea racemosa, Ranunculaceae) in addition to Foster’s epic 22-page article, titled “Toward an Understanding of Ginseng Adulteration: The Tangled Web of Names, History, Trade, and Perception.”
In 2012, ABC introduced an online “page-flip” version of HerbalGram that is optimized for viewing on smartphones, tablets, and computers. In 2016, all issues of HerbalGram became available in PDF format, from 1983’s issue 1 through the current issue, thanks to a digitizing project overseen by Art Director Matt Magruder in 2016. Before that, only issues 85 and above were available as PDF files.
HerbalGram is available as a benefit of ABC membership at the Individual level and up. It also is sold in some bookstores and natural food stores.
Native to Argentina, Brazil and Paraguay, Passiflora caerulea, is one of three semi-hardy species of passionflowers, and is widely cultivated as a window box plant or gardens in southern Europe, surviving temperatures of -15°C. It was cultivated in France as early as 1625, and first document in London in 1629. Today it is one of the most widely-grown passionflowers in horticulture, and source of many hybrids. These photos were taken in a garden in Podgorica, Montenegro.
Intent on reaching the swimming hole on a seething July afternoon, my attention was diverted by a loud pop under foot. Relieved by the realization that the object was vegetable rather than animal, the victim plant caught my attention again, this time by the indescribable, intricate beauty of its bloom. I had stepped on a fruit of the passionflower or maypop. Such is the memory of a New England transplant upon first encountering a maypop in the Ozarks. This fast-growing perennial vine is more widely known as passionflower (Passiflora incarnata). In the Southeast it’s also called apricot vine.
Passionflower’s Name
What design of nature or serendipitous evolutionary event could create a flower of such unusual beauty? Such radiance is beyond scientific rationale. Best to describe it in religious terms. The first Europeans to observe the plant did just that. The name is derived from flos passionis, a translation of fior della passione, a popular Italian name which was applied to the plant to signify religious symbolism. The floral structure was seen to symbolize the implements of the crucifixion—the Passion of Christ— his period of suffering following the Last Supper and the Crucifixion. The three spreading styles atop the stigma were thought to represent the three nails by which Christ was attached to the cross. The five hammer-like anthers atop of the stamens exemplify the hammers used to drive the nails, or to others, Christ’s five wounds. Beneath these floral structures is a fringe of colored filaments, known as the corona. It was believed to depict a halo or perhaps the crown of thorns. Beneath it sits the corolla—with ten petals, each representing the ten apostles at the Crucifixion— save Peter and Judas. Some early missionaries envisioned that the bell-shaped, unopened or recently closed flower held these sacred symbols from the view of heathens who had not yet been converted to Christianity. If that’s not enough, the lobed leaves and long green vines further represent the hands and whips of Christ’s prosecutors. And so, both the common and Latin names—passionflower (Passiflora)—speak of these mysteries. Thomas Johnson editor of the 1633 edition of Gerarde’s Herball described these notions for what they were: “The Spanish Friers for some imaginarie resemblances in the floure, first called it Flos Passionis, The Passion floure, and in a counterfeit figure, by adding what was wanting, they made it as it were an Epitome of our Saviors passion. Thus superstitious persons semper sibi somnia fingunt” [always see contrived images]. The species name of passionflower “incarnata” means “made of flesh or flesh-colored.” Maypop, of course, refers to the fruits, the shape and size of a hen’s egg, which open with a resounding pop when squeezed.
Passiflora incarnata, Passionflower, or Maypop. Passionflower is variously wildflower, weed, ornamental perennial, delectable edible, or medicinal herb. The fruits, “maypops”, are edible. The whole above ground plant is considered a mild nerve sedative and a sleep aid. When tension, restlessness and irritability result in difficulty in falling asleep, passionflower is an herbal remedy of choice.
Passionflower Diversity
Depending upon your perspective passionflower is wildflower, weed, ornamental perennial, delectable edible, or medicinal herb. The flowers of one hybrid P. x alatocaerulea (a cultivated hybrid between P. alata and P. caerulea) are used in perfumery. That covers all the bases of the definition of an herb— any plant or plant part used for culinary, fragrant or medicinal purposes. Therefore, it deserves a place in herb gardens. Here we will primarily focus on the common maypop, wild passionflower, or apricot vine (P. incarnata) the only native species that is hardy and can be widely cultivated in much of the U.S.
Yellow Passionflower, Passiflora lutea one of the most diminutive of all passionflowers, with blooms barely reaching 2cm in diameter. It occurs from Pennsylvania to Florida, west to Texas, northward to Illinois.
The passionflower (P. incarnata) is an herbaceous perennial, trailing or climbing, with tendrils. The white to blue purple flowers are up to three inches across. It occurs in waste ground, along fence rows, roadsides, and fields from Pennsylvania to southern Florida, west to east Texas and north to southern Missouri, and Ohio. In the United States we have about 25 native or naturalized species of Passiflora, but only the passionflower and its diminutive relative wild yellow passionflower (P. lutea), with tiny yellow flowers about an inch across, are hardy natives. Wild yellow passionflower is rarely grown in gardens.
The genus Passiflora, with only a handful of temperate species, explodes in diversity in the American tropics with about 500 species. An additional 20 species occur in Indomalaysia and the south Pacific islands. Some have edible fruits. Others do not. About 30 species of passionflower have edible fruits. At least 40 species and numerous cultivated varieties are found in American gardens, primarily in warmer areas.
Passiflora edulis, passion fruit, passionfruit is used as a commercial source of passionfruit beverages in the tropics. Since the fruits have poor keeping qualities they are seldom seen outside of local tropical markets. A folk remedy for insomnia, neuralgia, muscle spasms and epilepsy. Juice considered a digestive aid.
The undisputed edible king of passionflowers is passionfruit or purple granadilla (Passiflora edulis) which is cultivated for its edible fruits and juice. It is native to southern Brazil, Paraguay and northern Argentina. A large passionfruit industry in Brazil grows purple-fruited forms for the fruits, while yellow-fruited cultivated forms are used for juice extraction. Passionfruit is grown commercially in Australia, New Zealand, Hawaii and other tropical regions. It was introduced into Hawaii in the 1880s, where it became a popular home garden flower and fruit on the islands. By the 1930s it had become wild on every island in the archipelago. Commercial cultivation operations are also found in Kenya, South Africa, India, Pacific islands, and other tropical regions where it thrives. According to Arthur O. Tucker passionfruit has proven hardy in protected situations as far north as Ontario. If you do buy seeds or plants of this species and don’t live in a subtropical area, you will probably want to bring it indoors for the winter. The vast majority of scientific references to Passiflora species refer to the passionfruit and its many cultivars and hybrids. Much of the research has focused on attempting to unlock the unusually complex, sweet, delicate-perfume flavor of the fruits.
Other passionflowers are grown as subtropical food plants as well. The tropical American species running pop (P. foetida), now a weed in the old world tropics, is grown for its fruit, as is the banana passionfruit (P. mollissima). Yellow granadilla, or water lemon (P. laurifolia), also known as Jamaica honeysuckle, is a commercial fruit crop. Its name does not derive from any resemblance to honeysuckle (Lonicera species) but from the fact that the fruits are eaten by sucking out the pulp from the rose-scented fruit. Sweet calabash (P. maliformis) is grown to produce grape-flavored juice. Giant granadilla (P. quadrangularis) sports a large fruit about eight inches long which is eaten as a vegetable. Individual fruits of cultivated varieties of giant granadilla may weigh as much as several pounds. When still green the rind is boiled and eaten as a vegetable. If ripe, it is eaten iced (with sugar) or the fruit-wall may be candied. Members of the genus Passiflora hybridize readily and have produced numerous cultivated hybrids, primarily grown in the tropics for fruit production.
Passiflora vitifolia, Grapeleaved Passionflower, Crimson Passionflower is a showy native to Central America. The berry-like fruit is sour, then slowly ripens over a month a flavor likened to sour strawberries.
Other passionflowers such as red-flowered species P. vitifolia which sports crimson red flowers, or blue passionflower (P. caerulea) are grown as ornamentals. They do not produce edible fruits. Some cultivars of the blue passionflower such as ‘Constance Elliot’ which sports white flowers, are reported to be hardy in protected situations as far north as central Delaware. The tender ornamental passionflowers can be grown as annuals, taking cuttings in late summer rooting them before the first frost, or growing them in a large container to winter it over.
Native to Argentina, Brazil and Paraguay, Passiflora caerulea, is one of three semi-hardy species of passionflowers, and is widely cultivated as a window box plant or gardens in southern Europe, surviving temperatures of -15°C. It was cultivated in France as early as 1625, and first documented in London in 1629. Today it is one of the most widely-grown passionflowers in horticulture, and source of many hybrids. These photos were taken in a garden in Podgorica, Montenegro.
Growing Passionflower
Subtropical edible or ornamental passionflowers are primarily relegated to the realm of the specialized collector, or those who have access to a greenhouse. But the passionflower (P. incarnata) can be grown by most herb gardeners. While passionflower is commonly regarded as a southern plant, it will grow as far north as the Boston area, and I suspect, if placed in a well-protected situation and mulched through the winter, it would even survive as a perennial in central Maine. Here in the Arkansas and Missouri Ozarks, the native passionflower withstands temperatures of -25° F. without any protection. When purchasing seeds or plants it’s probably a good idea to at least inquire where the plant material originated, if the seller knows. Passionflower seeds or plants from south Florida are probably likely to survive in New England, than plants originating from more northerly areas. While dying back to the ground each year, it makes a marvelous fast-growing climbing cover for a fence, or can be trained on a trellis as a focal point for the herb garden. In the South it will grow 20—30 ft. in a single season. In more northerly areas, expect a growth of about 15 feet in a season. Passionflower grows in waste places, thriving in relatively poor, sandy, acidic soils. Good drainage is essential. Full sun is necessary.
Propagation is by seeds, cuttings, or layering. Cuttings about six inches in length can be taken from mature plants, then rooted in sand. Maypop grows readily from seed—if one has patience. After harvesting the fruits, clean out the seeds from the mucilaginous fleshy aril surrounding them, then plant immediately. They may germinate late in the summer, or may sit dormant until the following spring. The experience of many who try passionflower from seed for the first time is disappointment, born of expectations that the seeds will germinate in a couple of weeks. Wait a year if you have to. The result of your patience and suspense will be worth it a few years later.
Propagation by layering can be achieved simply by removing the leaves from a small section of a stem in late summer, placing a portion beneath the soil, with a leafy end sticking out of the ground. Water well, and in a few weeks, the buried stem should produce roots. But wait. Keep the layer in the ground through the dormant months, allowing it to develop a full root system before transplanting. The layered cutting can be severed from the mother plant and placed in a new location. With a little luck and persistence, you will soon have your own passionflower planting. Of course, the easiest technique is simply to buy plants from a nursery. Young plants are often slow-growing, taking two or three years to establish. After that, watch out—it can entangle everything else in your perennial beds.
Passionflower as Food
In his “Thousand Mile Walk to the Gulf” John Muir speaks of the apricot vine (maypop) has having a superb flower “and the most delicious fruit I have ever eaten.” If you grow passionflower, you must taste the fruits. The fruits of the passionflower ripen from yellowish to light brown in color. The slimy aril covering the seeds is very sweet and fruity when ripe. The hard seeds can be separated from the pulp through a sieve or apple sauce strainer. Or if you are in the garden, you can pop open the ripe fruit and suck the delicious pulp from the fruit. Make sure that the fruit is not over-ripe. Perfectly ripe fruits are delicious . Over-ripe fruits ferment into a foul paste.
Passionflower, Passiflora incarnata
At the annual funding-raising auction of the Arkansas Native Plant Society a few years ago, I was the fortunate high bidder on two jars of maypop jelly. I know of no other native fruit whose flavor is best described as “indescribable.” The best maypop jam recipe can be found in Billy Joe Tatum’s Wildfoods Field Guide and Cookbook (Workman Publishing Co., Inc., New York 1976). Billy Joe’s book, which transformed wild edible from the realm of survival food to haute cuisine, also contains a delicious recipe for maypop punch, and maypop ice, a cool refreshing beverage with juiced maypops and pineapple sherbet. To make 10 half-pint jars of maypop jam, she combines 5 cups of gently rinsed maypops, with a 1/2 cup of lemon juice, one box of powdered pectin and 7 1/2 cups of sugar. Enough water is added to barely cover the fruit. Standard procedures for making jam are followed.
Passionflower was a minor food item of American Indian groups in the Southeastern U.S. Archaeological evidence shows that maypop seeds could be found at Indian camp sites over 5000 years old. Seventeenth century visitors to Virginia such as the Englishman William Starchey observed the harvesting of fruits from corn fields. Calling it maracock, Starchey described it as “of the bigness of a green apple, and hath manie azurine or blew kernells, like as a pomegranat, a good sommer cooling fruit.” It is unclear whether native groups intentionally planted the passionflower as a crop or whether it simply occurred naturally on the disturbed ground at the edge of the plot. It is clear, however, that native groups of the Southeast enjoyed this late summer fruit for many centuries.
Passionflower as Medicine
Passionflower, Passiflora incarnata
Passionflower never became an important medicinal plant in the U.S. Like many American medicinal plants, however, it is more highly revered in modern Europe than in its native land. In the second volume of his 1830 Medical Flora or Manual of Medical Botany of the United States the naturalist Constantine Samuel Rafinesque makes one of the earliest reference to medicinal use. He recommends a syrup of the fruits as a cooling agent for fevers. The leaves, he says are used externally, and the juice given to dogs to cure the “staggers or epilepsy.” This use was first recorded in 1787 by a German surgeon, Johann David Schoepf, who served with Hessian mercenaries siding with the British during the Revolutionary War.
In Europe, passionflower products are used as mild nerve sedatives and a sleep aid. The introduction of this medicinal use is credited to Dr. L. Phares of Mississippi who in an 1840 issue of the New Orleans Medical Journal, recorded its use. Remaining an obscure reference in the literature, Dr. I.J.M. Goss of Atlanta reintroduced passionflower into Eclectic medical practice in the late nineteenth century.
Dr. E. D. Stapleton writing in a 1904 issue of the Detroit Medical Journal summed up his experience in using passionflower tincture to treat insomnia “I would say that its action is best obtained in cases of nervousness due to causes other than pain-that it is slow in acting because it is not a narcotic, but a nervine and sedative. It relieves irritation of the nerve-centers and improves sympathetic innervation, thus improving circulation and nutrition, and is as a rule sure in its results-no bad after-effects, no habits formed”.
In the eighteenth edition of King’s American Dispensatory (1898), authors H.W. Felter and J.U. Lloyd characterize its action. “Its force is exerted chiefly upon the nervous system, the remedy finding a wide application in spasmodic disorders and as a rest-producing agent. . . It is specially useful to allay restlessness and overcome wakefulness, when these are the result of exhaustion, or the nervous excitement of debility. It proves specially useful in the insomnia of infants and old people. It gives sleep to those who are laboring under the effects of mental worry of from mental overwork.” Sounds like I need some myself.
Yellow Passionflower, Passiflora lutea, with fruits the size of a pea. It occurs from Pennsylvania to Florida, west to Texas, northward to Illinois. Although yellow wild passionflower is very rarely mentioned in the medicinal plant literature, in 1840 Dr. L. Phares of Mississippi is said to have used this small North American vine interchangeably with the common passionflower.
It is interesting to note that while yellow wild passionflower (P. lutea) is very rarely mentioned in the medicinal plant literature, Dr. Phares of Mississippi is said to have used this small North American vine interchangeably with the common passionflower. I have made a tincture (alcohol extract) of both plants. They have a very similar flavor and fragrance. The fruits are decidedly different, though. Those of P. lutea are globular black berries, about 1/4 inch across. They have a much more acidic flavor than maypop.
Herbal Medicine Past and Present by John K Crellin and Jane Philpott (Duke University Press 1990) is based on extensive interviews over a seven year period with an Alabama herbalist, Tommie Bass. Bass, quoted in the text says, “Its the most wonderful sleep and pacifying plant, valuable for a nerve medicine . . . Any good sleeping medicine has passion-flower in it.”
Today the American passionflower is used in a number of proprietary phytomedicines (plant medicines) in Europe, used for “conditions of nervous anxiety.” A dosage of 4-8 g. of the herb per day in infusion (tea) or other methods of preparation such as equivalent extracts for internal use. Products are made from the fresh or dried whole plant (excluding the root). It is usually collected at flowering time. It is also widely used as a sleep aid. The fresh or dried whole plant as well as their preparations are also used in daily dosages equivalent to 0.5 to 2 g. of the herb, or 2.5 g in tea (about a teaspoon of the dried, ground herb). Preparations include tea, tinctures, fluid extracts, solid extracts, and even sedative chewing gums. Passionflower is also combined with valerian and hawthorn in products used in Europe to treat digestive spasms, gastritis, and colitis.
Like many medicinal herbs, the exact chemical components responsible for the plant’s sedative activity have not been definitively identified. Researchers have found small amounts of components known as harmala-type alkaloids in the plant, as well as compounds called flavonoids. In Germany, passionflower preparations were regulated to contain no more than 0.01 percent of harman alkaloids. Some believe the flavonoids to be active compounds. Still other researchers believe that substances known as maltol and ethyl-maltol may be responsible for the sleep-inducing and muscle relaxant activity attributed to passionflower. Generally it is believed that the sedative effect is probably a result of an interaction between the alkaloids and flavonoids found in the extract.
While the active constituents and mechanism of action of passionflower requires more studies, various studies confirm a sedative effect on the central nervous systems. The degrees of effect is dependent upon dose. Extracts of the herb inhibit fungi and bacteria. Studies indicate that the herb (or its extracts) relieves spasms, has a sedative effect, allays anxiety, and lowers blood pressure. The experience of numerous medical practitioners and herbalists in Western herbal traditions generally confirm the plant’s safety and efficacy.
Most of the supply of dried passionflower leaves either cultivated or wild-harvested in the U.S. goes to the European market. Farmers treat it as a weed in the South. USDA scientists focus on developing it as a new fruit crop for the U.S. Gardening enthusiasts appreciate the passionflower and subtropical passionflowers for their fantastic, colorful floral assemblage. Wild food enthusiasts, delight in its delicate, delectable flavor. And if you are a herb gardener, you’ll undoubtedly enjoy adding passionflowers to your herbary.
Yellow Passionflower, Passiflora lutea, a member of the Passifloraceae or passionflower family, a predominantly Neotropical American plant group of about 500 species, with three temperate North American representatives including, Passiflora lutea.

I’m dreaming of a bright Christmas—sunny with temperatures approaching the low 70s. The iconic “White Christmas” is so 1940s! Forget the fact that Bing Crosby’s version of Irving Berlin’s song is the best-selling single of all time. A white Christmas is a historical song from 1941. We must look on the bright side of global warming as it relates to “climate change.” We just need to change our perspective. Speaking with my 87-yr old dad in Maine, he remarked that as a kid, he and his friends were always skating by Thanksgiving. I reminded him, that we—his kids—were also skating by Thanksgiving! During my Maine childhood a white Christmas was a given. Now, ponds and lakes barely hold ice in some Maine winters. But of course, a Maine winter is why this Maine native lives in the Ozarks.
Spring Street, Eureka Springs, Arkansas, Ice Storm 2009
Every time I experience, feel, and see beauty in nature, I am humbled and awed. I love how water changes into myriad forms of beauty in ice. I also love each and every strand of evolving, changing, adapting, mutating DNA that is The creator’s building block of creation. I don’t believe in DNA, the stuff of The creator’s evolutionary magic. I don’t have to. It exists whether I choose to believe in it or not. Recent religious thought teaches us that the Earth is flat and the Earth is the center of the Universe. And “recent” I define as what historians calls the “early modern era” beginning about 1500. As one historian friend put it, “Anything that happened after 1500 is by definition current affairs.” I don’t believe in global warming. I don’t have to believe in it. Science has blessed me with a magic wand known as a thermometer. Burn me at the stake.
The beauty of snow, sleet and freezing rain
Spring Street, Eureka Springs, Arkansas, Ice Storm 2009
Which brings me to snow, sleet and freezing rain, and what differentiates them. Snow is created when a mass of cold, freezing air is uniformly below freezing from the Earth’s surface to the upper atmosphere. Sleet
Crescent Hotel, Ice Storm, January 29, 2009
is formed when the air aloft is like a sandwich. In this case, the upper levels of the atmosphere are below freezing and when it snows, the snow passes through an atmospheric layer above freezing, causing the snow to partially melt. It then passes through a relatively shallow layer of below-freezing air at the surface, creating sleet. Freezing rain forms when rain from warm air aloft reaches below-freezing surfaces at ground level, caused by a shallow layer of cold air at the surface. Expect to see plenty of all three types of frozen precipitation this winter—courtesy of global warming.
Hoar Frost Beauty

And I love the beauty that all that ice in it’s myriad form creates. Take hoar frost for example. We’ve had beautiful hoar frost (also known as hoarfrost this year. But what is hoar frost? I turned to the website of the National Snow and Ice Data Center for a definition “Hoarfrost: A deposit of interlocking ice crystals (hoar crystals) formed by direct sublimation on objects, usually those of small diameter freely exposed to the air, such as tree branches, plant stems and leaf edges, wires, poles, etc., which surface is sufficiently cooled, mostly by nocturnal radiation, to cause the direct sublimation of the water vapor contained in the ambient air.”
Hoarfrost, therefore, is like dew, except when it’s cold enough outside to freeze water (that is when it’s 32°F or 0°C), and there’s moisture in the air, then hoar crystals (flat crystals that interlock together), form from the moisture in the air when it comes in contact with the edge of the object that is below freezing (or vice versa?). So if you get up early enough, especially after a clear cold night, you can experience the direct sublime beauty of hoarfrost in all its simplicity.

Another winter beauty phenomena I love is frost flowers and ice ribbons. Perhaps new to your natural history vocabulary, we can also call this phenomena “crystallofolia,” a term coined by Bob Harms of the Plant Resource Center, University of Texas, Austin, who has been investigating the phenomena we commonly call “frost flowers”— those beautiful ice formations that are produced at the base of only two native plant species in my Ozark home. Our two native plant species that exhibit this phenomenon are American dittany (Cunila origanoides) and white crownbeard or frostweed (Verbesina virginica) both of which are late-blooming wildflowers. Their frost flowers or twisted ribbons of ice appear for a few days (up to a couple of weeks) after the first hard freezes in autumn. These ephemeral sculptural beauties in ice appear at the base of the plant.

The delicate, elegant ice formations emerge laterally from the stem, just above the ground in the case of American Dittany, but from ground level to two feet up the stem in the case of white crownbeard. Why does this phenomenon only occur in a select few plant species instead of all plants? Speculation is that a combination of characteristics unique to the plant in combination with the external physical forces provides a perfect opportunity for the frost flowers to develop. The xylem, vascular tissue within plants that helps conducts water upward in the stem, is probably quite firm, with secondary rays at a right angle that is strong enough to conduct water during a frost event but its tensile strength reaches a point during the first cold frosts, that freezing water burst through the epidermis at a right angle to the stem. As it does so, it ever so slowly punches moisture into the freezing air extruding ribbons of ice. I love these beauties of nature.
Pennsylvania physician, William Darlington (1782-1863) seems to be one of the first to record observations of frost flowers in Cunila, or as he called it, Maryland Cunila. In the second edition (1837, p. 350) of his Flora Cestrica (an herborizing companion for the young botanists of Chester County, Pennsylvania) he writes: “In the beginning of winter, after a rain, very curious and fantastic ribbands [sic.] of ice may often be observed, attached to the base of the stems of this plant—produced, I presume, by the moisture from the earth rising in the dead stems by capillary attraction, and then being gradually forced out horizontally, through a slit, by the process of freezing. The same phenomenon has been noticed other plants.”

Predicting When Hell will Freeze Over
How do you survive a cold winter? Perhaps the best way, short of a long trip to a tropical location or being condemned to a mythical inferno, is to get a comparative perspective on someone else’s cold winter. In the English-speaking world we can turn to England, which has the longest series of monthly temperature observation datasets recorded back to 1659. This dataset is known as the CET (Central England Temperature), recorded in Celsius.

The winter of 1683-84 is believed to be the coldest winter since records have been kept, with a “great frost” settling in by mid-December for the UK and Central Europe. By January of 1684, the Thames River was frozen all the way up to London Bridge. The Thames itself remained frozen for over two months, with ice measured to a depth of 11 inches. In southwest England, in Somerset, it is said that the ground froze to a depth of four feet. Southwest England, has a relatively mild climate, tempered by the Gulf Stream in the winter months, and Azores high pressure systems in the summer. The winter of 1684 had thee coldest CET at –1.2 deg. C. This period of cold winters lasted for several centuries. From 1408-1814, the Thames froze over 24 times; sometimes the ice was deep enough to support “frost fairs” on the Thames (the last one in 1814).
This is all within a period known as “the Little Ice Age”, a phrase first used in the scientific literature until 1939. It is loosely defined as a period from about 1350-1850, with three particularly cold periods around 1650, 1770 and 1850. Attributed causes include low cycles of solar radiation, increased volcanic activity and variables in ocean circulation.

Fewer sun spots may cause cooling. The years 1645-1715 represent a period of weak solar activity (fewer sun spots) known as the Maunder Minimum period (in which only one-thousandth of “average” expected sun spots occurred). This solar lull is theorized to have trigged regional cooling in the Northern Hemisphere. Since 2008 we have been in a period of “solar maximum” yet only half of the sunspot activity expected has occurred. This has led some scientists to speculate that we could be heading toward a period of “cooler “solar activity within the next 40 years. Add that into the global-warming equation, and you still get climate change
Chaste Tree (Vitex agnus-castus) has been used for gynecological conditions since the days of Hippocrates (2500 years ago). With a rich traditional of use, modern research supports historical wisdom, and has made chaste tree fruit preparations a phytomedicine of choice by European gynecologists for treatment of various menstrual disorders, PMS, and other conditions.
Origins and Botany
The genus Vitex until recently has been associated for centuries with the verbena family (Verbenaceae), and includes about 250 species, primarily tropical shrubs and trees. Only a few Vitex species occur in temperate regions. Vitex agnus-castus L., commonly known as chaste tree, is the sole species to occur in Europe. Native to West Asia and southwestern Europe, the shrub was introduced throughout Europe at an early date. It was known in English gardens as early a 1570, and now occurs throughout the European continent.
Chaste tree is a shrub growing from nine to seventeen feet tall, though specimens twenty-five feet high, with trunks eight inches in diameter, have been recorded. It has palmate leaves, usually with five to nine (rarely three) leaflets, white hairy beneath, with densely hairy, resinous leaf stalks. The flowers are in a pyramidal-shaped showy cluster, with seven inch spikes, sporting tiny blue to lilac blooms. Chaste tree has a long blooming period, as early as April in the deep South, lasting into October in more northerly areas in the United States. Typically it blooms from June through August. The small round fruits (seeds) have a pungent scent and flavor. Introduced to American gardens by European immigrants in the early nineteenth, the shrub has become naturalized in much of the Southeastern United States, occurring in Florida, Georgia, Alabama, Mississippi, Louisiana, Arkansas, Texas, southeast Oklahoma, north to Maryland.
The genus name Vitex derives from an ancient designation, vei, meaning to “wind, bend or twine,” referring to the once common use of the tough, flexible branches in constructing woven (wattle) fences. Pliny was the first to apply the name Vitex to the plant, perhaps derived from the Latin “vitilium” (wicker-work). The species name “agnus-castus” derives from a historical mis-interpretation of the original Greek name, “ágnos,” first applied by Dioscorides, and translated as “holy, pure or chaste,” Castus derives from the Latin castitas, meaning chastity. Agnus the Latin for lamb, at some point in history, replaced the original Greek “agnos” in reference to this plant (Böhnert and Hahn 1990).
History
Chaste tree has been used for the treatment of menstrual difficulties for at least 2,500 years. The Greek physician Hippocrates (460-377 B.C.) wrote, “If blood flows from the womb, let the woman drink dark wine in which the leaves of the chaste tree have been steeped. A draft of chaste leaves in wine also serves to expel a chorion held fast in the womb” (as quoted by Bleier 1959). Use for gynecological conditions are also noted in the works of Pliny and Dioscorides (1st century A. D.), as well as Theophrastus (3rd century A.D.). “The trees furnish medicines that promote urine and menstruation,” wrote Pliny, “They encourage abundant rich milk. . .” (Jones 1966).
Dioscorides, quoted from Goodyer’s 1655 English translation, recognizes effects on females, “It doth brings downe the milke, and expells ye menstrua, being drank to ye quantity of a dragme in wine” (Gunther 1934). These recommendations survive to the time of Gerarde, “The decoction of the herbe and seed is good against pain and inflammations about the matrix, if women be caused to sit and bathe their privy parts therein; the seed being drunke with Pennyroiall bringeth downe the menses, as it doth also both in a fume and in a pessary. . .” (Gerarde 1633).
Chasteberry
The tree was associated with ancient Greek festivals. In the Thesmophoria, a festival held in honor of Demeter, the Greek goddess of agriculture, fertility and marriage, women (who remained “chaste” during the festival), used the blossoms for adornment, while bows of twigs and leaves, were strewn around Demeter’s temple during the festival (Böhnert and Hahn 1990). Pliny wrote, “the Athenian matrons preserving their chastity at the Thesmophoria, strew their beds with its leaves.” (Jones 1966). In Rome, vestal virgins carried twigs of chaste tree as a symbol of chastity. According to Greek mythology, Hera, sister and wife of Zeus, regarded as protectress of marriage, was born under a chaste tree. Ancient traditions associating the shrub with chastity were adopted in Christian ritual. Novitiates entering a monastery walked on a path strewn with the blossoms of the tree, a ritual that continues to the present day in some regions of Italy (Böhnert and Hahn 1990).
The shrub’s ancient association with chastity led to later use of the fruits as an anaphrodisiac, quieting the desires of the flesh, especially of celibate clergy. “These seeds have been celebrated as antiaphrodisiacs, and were formerly much used by monks for allaying the venereal appetite; but experience does not warrant their having any such virtues,” wrote Andrew Duncan in the 1789 edition of the Edinburgh Dispensatory.
Robert John Thorton (1814), put it more eloquently, “As there are provocatives to procreations, as shell-fish, eggs, and roots of orchises made into salep for the male, and spare dict and use of steel for the female, so it is possible the chaste tree may have a contrary effect; and hence the seeds have been called Piper monachorum (Monk’s pepper), who flew to them when they found the spirit to be willing, but the flesh weak.”
Many of the common names of the shrub refer to this use of the plant, including, Abraham’s Balm, Chaste Lamb-Tree, Safe Tree, Monk’s Pepper-Tree. It has also been called Indian-Spice, and Wild-Pepper, referring to the use of the fruits as a pepper substitute. The small round fruits (seeds) have a pungent scent and flavor reminiscent of black pepper. The fragrant leaves have also been used as a substitute for hops in brewing beer.
Through the eighteenth and nineteenth century, the fruits were little used by European medical practitioners. In the late nineteenth century, Felter and Lloyd (1898) suggested use of a tincture of the fresh berries to Eclectic medical practitioners to increase milk secretions and useful as an agent in menstrual disorders. In small doses, it was said to be useful in the treatment of impotence, and perhaps useful for nervousness or mild dementia.
Early Modern Research (1938-1960)
Madaus (1938) was the first to initiate use of chaste tree in the twentieth century. Recognizing the long-recognized value of the plant in gynecological disorders, he designed a series of animal experiment to determine which part of the plant had the greatest biological activity. Madaus found that extracts of the leaves, fruits, and bark retarded estrus (heat) in female rats, without evidence of adverse effects on reproductive performance. The fruits had the greatest activity.
Chasteberry
During the Second World War, medical practitioners in Germany recognized a stress-induced lactation repression in women, prompting a search for effective galactogogues (milk stimulating substances). Clinical confirmation of the efficacy of chaste tree fruit preparations in stimulating lactation were published in three separate papers by Janke, Hofmeir and Noack and Noack in 1941, 1942 and 1943 respectively (as reviewed by Böhnert and Hahn 1990). Later animal studies in the late 1950s further confirmed an experimental lactation-stimulating action. In 1954, Mohr reported on a study of 1000 maternity patients, comparing vitamin B1 and a chaste tree fruit preparation in stimulating lactation to a placebo. The author concluded that the chaste tree fruit preparation resulted in more successful lactation than vitamin B1 or the control group. Increased lactation has been attributed to an increase in prolactin secretion, increased progesterone synthesis, reducing estrogen secretions (which tend to inhibit milk production).
Active constituents and Actions
Results of these early studies led investigators to postulate that either the plant contained a component that replaced hormones produced by the body, or plant extracts, acting through the pituitary, might regulate hormone production (Haller 1961). Various studies, reviewed by Böhnert and Hahn (1990), indicate that a tincture of the seeds produces an effect on the hypothalamus-pituitary system, showing a gonadotropic function and causing an increased release of lutenizing homone with consecutive increase of progesterone level. Prolactin secretion is inhibited because of a dopaminergic action. In other words it acts on the pituitary gland to regulate the production of and induce normalization of the ovarian hormones, changing the ratio of estrogens and gestagens in favor of gestagens. The timing of the release of pituitary hormones, regulate menstruation, fertility, and other processes. Hence, an agent that will produce a balance of hormones can help to regulate these processes.
The biological activity of chaste tree cannot be attributed to a single chemical component. The fruits contain flavonoids including the major flavonoid casticin, as well as orientin and isovitexin (Belic et al., 1958, 1961, 1962). Other flavonoids include 3,6,7,4’-tetramethyl ether of 6-hydroxykaempferol, and quercetagetin (Wollenweber and Mann 1982). The dried fruits also contain an essential oil (up to 1.22%), as well as iridoid glycosides including aucubin, eurostoside and agnuside among others (Görler et al., 1985, Gomma et al. 1978). A recent study detected the probable presence of delta-3-ketosteroids in flower extracts include progesterone, 17-a-hydroxyprogesterone, testosterone, and epitestosterone; leaf extracts yield andostenedione. However, the reported results of this study were ambiguous (Saden-Krehula, et al. 1990). The vast majority of chemical, pharmacological and clinical studies have involved a proprietary extract, Agnolyt®, (capsules and liquid) manufactured by Madaus AG, Cologne, Germany.
Chasteberry, like the rest of the 250 species of Vitex, long-placed in the verbena family (Verbenaceae) now in a genetic surprise twist are placed in the mint family (Lamiaceae).
Modern Clinical Use
An imbalance of estrogen and progesterone has also been associated with premenstrual syndrome (PMS). Symptoms appear seven to ten days before the beginning of menstruation, and cease once the cycle begins. Physical symptoms include painful breasts, abdominal discomfort and fullness, flatulence, edema (especially of the lower extremities, as well as the hands and the face), and headache. Mental symptoms may include mood swings, nervous irritability, depression, restlessness, and aggressiveness. It is estimated that between 5 and 30% of women may be affected by PMS. Therapeutic choices by health care professionals are based on severity of symptoms. In severe cases, the treatment of choice is likely to be steroidal hormones. In Europe, however, gynecologists have another choice, preparations made from the fruits of the chaste tree (Feldmann).
A clinical survey of German gynecologists published in 1992 evaluated the effect of a chaste-tree preparation (Agnolyt®) on 1542 women diagnosed with PMS. Treatment of 40 drops daily lasted an average of 166 days. Both physicians and patient assessed efficacy, with 90 percent reporting relief of symptoms, after an average treatment duration of 25.3 days. Two percent reported side effects, mostly gastrointestinal in nature (Dittmar et al 1992, Brown 1994).
In one clinical drug monitoring study of the efficacy and safety of long-term treatment with a chaste tree fruit tincture, 1571 women with menstrual disorders including corpus-luteum insufficiency and PMS were followed for a period of 7 days to six years (average 147.6 days). The preparations was 1:5 tincture, with a 58% alcohol content. The dose was 40 drops once a day taken on an empty stomach in the morning with water. In 90 percent of patients, the treatment eliminated or alleviated symptoms of PMS. Results for 465 patients were rated very good, 714 good, 220 satisfactory, 110 unsatisfactory, and in 62 cases no data was available. Adverse reactions were reported for 30 patients (1.9 percent), including 12 cases of nausea, malaise, gastric symptoms and diarrhea, and a single allergic reaction (Feldmann, et al., 1990).
Coeugniet, et al (1986), in a three month trial with 36 patients with PMS reported positive results in physical and psychological symptoms. A dose of 40 drops a day, taken over a three month period, produced a reduction in headaches, breast tenderness and pressure, bloating, and fatigue. Improvement in anxiety, mood swings, and other psychological symptoms were also reported. Given the positive results of experimental studies in the 1940s and 50s coupled with clinical experience, has lead to the use of chaste tree extracts in European phytotherapy in several major areas including: management of menstrual disorders, PMS, treatment of infertility produced by mild corpus luteum insufficiency, and hot flashes at the initial stages of menopause, among other conditions.
In Europe, the use of phytomedicines in the treatment of menstrual disturbances is often preferred over conventional treatment, if no contraceptives are indicated. Steroidal hormones are often considered unnecessary, and individual treatment initiated once differentiation has been made between cyclic and acyclic bleeding difficulties (Loch 1989). A benefit of chaste tree treatment is the relative lack of side effects compared with treatment with steroidal hormones. Another benefit is that the price of chaste tree preparation therapy is far below that of conventional treatment methods. The 1992 German Commission E monograph (now irrelevant as a regulatory document) on chaste tree fruits allowed use of preparations for menstrual disorders due to rhythmic disorders of menstruation, mastodynia (pressure and swelling in the breasts), and premenstrual syndrome. Preparations include alcoholic extracts of the pulverized fruits (tincture) formulated to an average daily dose equivalent to 30-40 mg of the seeds. No contraindications were listed. While no interactions with other drugs are reported, animal experiments indicate the possibility of interference with dopamine-receptor antagonists. Side effects noted include too early menstruation following delivery (resulting from activation of the pituitary), as well as rare instances of itching and rashes. Chaste tree preparations are contraindicated during pregnancy (Monograph Agni casti fructus).
In a review on the relationship between phytotherapy and orthodox medicine, Schilcher (1994) reports that an important reason for the acceptance of phytotherapy by many German physicians is the existence of the scientifically supported Commission E monographs (as cited above). He also notes that acceptance of phytotherapy rests with the fact that in Germany, their use is consider a component of orthodox medicine and not an alternative approach. In Germany chaste tree fruit preparations are considered a safe, effective, and low-priced tool available to, accepted by, and widely used by gynecologists.
Summary
Chaste tree, recognized for nearly 2,500 years in the treatment of gynecological conditions, has been widely used in European phytotherapy for over fifty years. The majority of clinical reports in that period have been non-controlled studies by gynecologists in clinical practice, who report positive results. Chaste tree preparations are frequently used in the safe and effective treatment of PMS, heavy periods, too frequent periods, acyclic bleeding, infertility, suppressed menses, and other conditions, many of which are linked to corpus luteum insufficiency. Vitex is an excellent example of a phytomedicine which serves as a low-priced tool in orthodox European gynecological practice, rather than an “alternative” treatment.

Often when I’m out on a group hike, we come across plants that some are surprised to see in Arkansas. One of those plants is yucca. In fact, that are five species of Yucca recorded from Arkansas, including two or three from Carroll County, depending upon botanical whim. Botanists are so adept at changing plant names, that if they were put in charge of naming planets, we would surely wake-up one morning to discover that we no longer live on a planet called Earth. Telling Arkansas’s five yucca species apart from one another takes a good deal of chin rubbing.
Yucca elata
Fortunately for lay-folk consumers of botanical knowledge, the common name yucca is the same as the genus name—Yucca. One species of Yucca here in Carroll County has a name that’s easy to remember —Yucca arkansana which is kin to Yucca louisianensis due to inbreeding or some other evolutionary exchange of genes in the pre-human past. In 2014, the late Dr. George P. Johnson, a botanist at Arkansas Tech in Russellville found Yucca freemanii in Miller County. Besides these three native species, Yucca filamentosa and Yucca flaccida occur here but are not native to Arkansas; they are naturalized. In other words, they were planted at some point and now grow and reproduce without the help of humans.
Mojave Yucca
In North America (north of Mexico) there are twenty-eight species of Yucca. Yuccas have been used for thousands of years for food, beverages, detergents, medicines, construction material, and especially as a fiber plant. During the First World War, 80 million pounds of yucca fiber were used to make course bags. The U.S. Navy used a special heavy paper made from yucca fiber during material shortages of the Second World War. Over the centuries, among indigenous groups of the American Southwest, yuccas were the foremost wild plants used for material necessities.
One National Park in California is named after a yucca (Yucca brevifolia) the 792,683-acre, Joshua Tree National Park. President Franklin Delano Roosevelt decreed it a National Monument in 1933. In that same year, a cousin of Roosevelt’s, Susan Delano McKelvey, published a paper on yuccas in the Journal of the Arnold Arboretum of Harvard University where she worked as a research associate and valued patron. So which came first, the President’s decree or his cousin’s interest in Joshua tree and other yuccas? Later, she wrote the definitive two volume work Yuccas of the Southwestern United States. My vote goes to Roosevelt’s cousin.

The workshop will focus on techniques for improving plant and nature photography while exploring tropical beauty and attaining a deeper understanding of how to relate to plants. The fee is $1300 (double occupancy) and $1600 (single room) that includes six nights accommodation, all meals and airport transfer. Round trip airfare from your originating airport to San Jose Costa Rica (SJO) is additional. To reserve your space email: grupos@fincalunanuevalodge.com.
Finca Luna Nueva Lodge features the best of tropical comfort including an ozonated swimming pool and solar heated Jacuzzi along with spa services. Delightful meals of Costa Rican-Asian fusion cuisine, served three times a day are included with the package. Much of the food is produced on the farm.
Finca Luna Nueva Lodge features well-groomed hiking trails, along with the Sacred Seed Sanctuary Semillas Sagradas, an ethnobotanical garden harboring over 250 medicinal herbs. The garden, first established in 1994, has evolved under the guidance of New York Botanical Garden ethnobotanist, Michael Balick, America’s herbalist-in-chief, Jim Duke, and Costa Rican ethnobotanist, Rafael Ocampo. This extraordinary collection of neotropical medicinal plants is under the care of Steven Farrell, President of Finca Luna Nueva and Biodynamic farmer extraordinaire. The garden serves as a model for the creation of other Semillas Sagradas ethnomedicinal gardens elsewhere, in an effort to preserve not only local biodiversity, but the indigenous traditions that are keepers of the knowledge. Rafael Ocampo and Michael Balick co-authored Plants of Semillas Sagradas: An Ethnobotanical Garden in Costa Rica (2009). The book can be downloaded as a pdf file at the Finca Luna Nueva website. And that’s just a taste of the botanical offerings. Turn around at any moment and you could see a three-toed sloth, emerald basilisk lizard, green iguana, red-eyed frog, toucan or morpho butterfly!
