Wild Ginger grows in colonies.

Wild Ginger grows in colonies under deciduous trees.

Wild Ginger is cantharophilic, sometimes myophilic or sapromyophilic.

Wild Ginger Blossom does not have petals only sepals.

Wild Ginger Blossom does not have petals only sepals.

If that’s all Greek to you it should be because it is Greek bastardized via Dead Latin into English. Canthrarophilic means pollinated by beetles, myophilic or sapromyophilic pollinated by flies. I suspect bees (melittophily) occasionally get in there as well. Wild Ginger grows close to the ground so the beetle has a chance.  The plant is also myrmecochoric meaning its seeds are disbursed by ants. We are told 11,532 species of angiosperms have seeds disbursed by ants.  Busy little beavers they are. An explanation:

Ant grabbing seed by its elaiosome.

Ant grabbing seed by its elaiosome.

Seeds that are spread by ants usually have a fatty appendage or attachment called an elaiosome, which the Wild Ginger seed has. It looks tasty to an ant so the ant carries the entire seed back to the nest. Then it detaches or eats the elaisome, or figures out the appendage is not edible and dumps the seed outside the nest. Ants are tidy. Soooo…. when picking wild ginger and any one of the 11,532 ant-distributed species expect to find ants nearby.

Asarum caudatum

Asarum caudatum, Long-Tailed Wild Ginger.

Wild Ginger, Asarum canadense, is found in eastern North America, Manitoba south excluding Florida, Texas and Nebraska. In western North America one finds Asarum caudatum, or Long-Tailed Wild Ginger, note flower at left. It’s roots can be used as a ginger substitute and leaves brewed into a tea. There is also something of a misnomer with the plants. Their roots are actually rhizomes, which grow horizontally where as true roots are usually vertical. There’s also some schizophrenia regarding its use, particularly Asarum canadense. Touted as an herb and flavoring et cetera there are also warning of toxicity. All things in moderation, see the Herb Blurb below. Its basic use is as a ginger substitute in cooking, a flavoring agent, and for making some candy. There are numerous medicinal claims.

Asarum canadense is said ah-SAR um  can-nah-DENSE, or ass-AIR-rum  can-nah- DENSE. Asarum is from the Greek Asaron which means hazelwort (Asarum europaeum.) Hazelwort is a common wild ginger in Europe. It is not consumed because it is an emetic and cathartic. Canadense means North America and was where the species was first located.  Caudatum (kaw-DAH-tum) means “tailed,” referring to long sepal appendages.

Green Deane’s Itemized Plant Profile: Wild Ginger

Don't confuse Wild Ginger with Hexastylix arifolia

Don’t confuse Wild Ginger with Hexastylix arifolia

IDENTIFICATION: Asarum canadense: A stemless colony-forming plant 4 to 6 inches high with two velvety, heart-shaped to kidney-shaped, attractively veined, dark green, basal leaves. Urn-shaped, purplish brown flowers to one inch wide on short, ground-level stems growing out of the crotch between the two basal leaves. Flowers (with three sepals and no petals) are often hidden by the leaves.  Don’t confuse it with a similar plant with greenish-purple flowers Hexastylix arifolia, which has more a triangular, evergreen leaf.

TIME OF YEAR: Flowers April to May, roots used anytime

ENVIRONMENT: Easily grown in average, medium to wet, well-drained soil, in part shade to full shade. Prefers constantly moist, acidic soils in heavy shade. Spreads slowly by rhizomes to form an attractive ground cover for shade areas. Found under trees but usually not conifers.

METHOD OF PREPARATION: Flowers and rootstock used as flavoring. Roots, fresh or dried, can be a ginger substitute. Candied by boiling the roots in sugar water until a syrup forms. Root then rolled in sugar. Syrup can be used on desserts and ice cream. Can also be made into a beverage to settle the tummy.

Prof. Daniel E. Moerman

Moerman (1986) says Native Americans used Asarum canadense medicinally to treat poor digestion, swollen breasts, coughs and colds, typhus and scarlet fever, nerves, sore throats, cramps, heaves, earaches, headaches, convulsions, asthma, tuberculosis, urinary disorders, venereal disease; as a stimulant, birth control, seasoning and charm. It was also used to strengthen other herbal concoctions and increase the appetite.

Some species of asarum also contain aristolochic acid. It is used in rat poison. The United States Food and Drug Administration and Health Canada warn against consuming Wild Ginger. Significant amounts can damage kidneys. Professor Merritt Fernald, wunderkind at Harvard for some 50 years, thought in moderation as a flavoring and spice it was okay.

Che berries are related to mulberries

Che is not the tree it used to be.

Che's thorns are inconsistent

Che’s thorns are inconsistent

At one time there were just he and she Che trees. Then a few decades ago along came a self-fertile seedless Che then Ches grafted onto a close relative the Osage Orange. The he’s and she’s have also escaped from cultivation in North Carolina and coastal Georgia. I don’t think the seedless escape. Ches are planted from about New York south and west. Your best chance of seeing one is in landscaping in the southern half of the United States and up the west coast. Whether to include Che as a wild edible was a bit of a debate. It’s wild in Asia and has been around North America for more than a century thus it was included. One reason why you might not have seen a Che is birds. They aren’t too interested in the berries so they don’t spread the tree around.

Leaf shape can vary from 3 lobs to none

Leaf shape can vary from 3 lobes to none

The Che is native from the Shantung and Kiangson Provinces of China to the Nepalese sub-Himalayas. It was naturalized in Japan many years ago which is where I first saw one back in the early 70’s. Che (Cudrania tricuspidata) was introduced to France in 1862, England in 1872 and to the United States about 1909. There was one growing at the P. J. Berckman’s Nursery in Augusta Georgia by 1912 and fruiting, which is another issue. Both male and female trees can fruit, she more than he while the grafted seedless fruits the most.

Che benefits from pruning

Che benefits from pruning

The seedless Che is a small tree. The natural species is shrubby and can produce many suckers. By grafting the Che onto an Osage orange a superior single-trunk fruit tree is created. It bears a large crop of red, juicy fruit clusters reminiscent of round mulberries about an inch through, ping-pong ball-ish in size. The flavor is a cross between a mulberry and a fig, which it not remarkable as it is related to both. It is also distantly related to Breadfruit (Artocarpus altilis), Jackfruit (Artocarpus heterophyllus), Fig (Ficus spp.), Mulberry (Morus spp.), African Breadfruit (Treculis africana), Paper Mulberry (Broussonetia papyrifera) and the aforementioned Osage Orange (Maclura pomifera.)

Bonsai Che

Bonsai Che

While the Che has been promoted outside of China as the up-and-coming fruit tree for decades in China its reputation varies from valuable to intolerable. This might be because of erratic thorns. The tree is backup food for the silkworm and the leaves have to be picked by hand which means braving thorns. Worse, the tree is not consistently thorny so there’s no pattern to help you avoid them. Silk made from the leaves, however, is reported to make high quality lute strings of pure tone. The Che is also a favored tree of for bonsai. (On a personal note a life time ago I visited Bonsai Machi in Japan, the heart of the bonsai culture. There were amazing specimens there. There was also a small city laid out with miniature buildings and bonsai tress for landscaping. The effect was to be a giant walking down the street. And when I see specials about bonsai they show specimens I saw some 40 years ago, still alive and craggy.)

Che berris store well

Besides “Che” the tree is called Cudrania, Chinese Mulberry,  Cudrang, Mandarin Melon Berry, Silkworm Thorn, and Storehousebush (why it is called that no one knows.)  As for the botanical name Cudrania tricuspidata no one knows where Cudrania came from either or what it supposed to mean. It was named by one Dr. Hance in 1877 and he left no clue as to why his chose that name for the genus. I suspect it has something to do with the common name of Cudrang. Tricuspidata means three pointed as in the leaves though even Dr. Hance said the leaves vary so much calling it Tricuspidata was inaccurate. “Che” (said like the Cuban revolutionary) means “stony ground,” a reference to the tree’s natural habitat of poor, dry soil. But it likes warm, rich soil as well.

Incidentally an intergeneric hybrid exist between the Che (Cudrania tricuspidata) and the Osage Orange (Maclura pomifera) called Macludrania hybrida. Mostly from France they were planted in the US National Arboretum in 1960 and have large orange-like fruit and no thorns.  Other than that planting the hybrid seems to have been largely ignored by everyone.

Green Deane’s Itemized Plant Profile: Che

IDENTIFICATION: Cudrania tricuspidata. Deciduous trees to 25 ft. height, often a broad, spreading bush or small tree.  rarely to 60 feet. Immature wood thorny, female trees larger than males. Leaves alternate, resemble mulberry but smaller, thinner, pale yellowish-green, trilobate, with central lobe sometimes twice as long as the lateral lobes, frequently unlobed. Flowers dioecious, male and female flowers on different plants, green, pea-sized. Fruit is aggregate, looks like a round mulberry crossed with a lychee, knotty, ripens to red or maroon-red, juicy, rich red flesh, 3 to 6 small brown edible seeds per fruit. Flavor varies from fig/mulberry cross to watermelon.

TIME OF YEAR: Flowers in late spring or early summer, fruit in early fall in cooler areas, later in warm areas. In warmer areas it is an evergreen. In cooler areas the leaves turn red in the fall and persist.

ENVIRONMENT: Likes a sunny, warm location with rich, well-drained soil but can grow in rocky dirt. Planted in zones 5-9, can tolerate -20F. Treat them like a mulberry tree. Fruit stains like mulberries.

METHOD OF PREPARATION: Trees mature early and can produce up to 400 pounds of chewy fruit. Let the fruit stay on the tree until they are soft and dead ripe. Ripening is continuous for about a month. Fruit is eaten out of hand or used like mulberries or figs. Good shelf life.

Grafts are better than raising trees from seeds. Seed planted immediately from ripe fruit germinate at a high rate. Stored seeds must have a period of cool, moist stratification. Plants from seeds can take up to 10 years to fruit. Cloned plants bear very young.

Corn smut cause infected kernels to swell

Corn smut cause infected kernels to swell

Mexican Truffles. Corn Truffles. Corn Smut. Raven Scat. Ustilago maydis gets more unappetizing the further one goes down its list of names. The Aztecs called it huitlacoche.  The Mexicans call it a delicacy.

CornSmut31c

Edible Corn Smut is used like cooked mushrooms

Corn smut is a fungus that grows on young maize. When the corn is in silk kernels become infected. They swell to golf-ball size galls and discolor. Loaded with soluble fiber, the amino acid lysine and the antioxidant anthocyanin, the moist young galls are collected two or three weeks after the corn becomes infected. If not harvested the galls will grow hard and spore-filled looking a smutty dark blue or black. The flavor of young galls is musty, earthy if not smokey. Less expansively they taste like a cross between mushrooms and corn. While the fungus is used like expensive mushrooms and served in elegant restaurants in Latin America it is considered a plant disease in other countries. If you can’t find any fresh locally you can order canned corn smut over the Internet. Perhaps not surprisingly fresh infected corn sells for more than uninfected corn. In the U.S. an ear of huitlacoche costs some 41 cents to produce and sells for about three times that, $1.20. An ear of sweet corn costs about a dime to produce but sells for only a few pennies more.

The Aztecs intentionally inoculated their corn with spores by scratching the base of corn stalk with a soil-smeared knife. In Midwest America hail scratches corn plants allowing spores to enter. The fungus can live up to three years in the soil. The intentional infection is usually manifests itself ten days to two weeks later.

Smut is canned for international sale. A 7 oz. can sells or about $11 plus shipping.

Smut is canned for international sale. A 7 oz. can sells for about $11 plus shipping. Fresh in Mexico it’s about $1.50 a pound, $20 a pound in the U.S.

Though highly nutritious there are reports of toxicity and effects such as fungal skin infection, hair loss and allergic reactions in people. There is little evidence to support that. However when digested Ustilago maydis is known to produce ustizein, guanacine, itaconic acid, ustilagic acid, and the alkaloid ustilagine, which may have similar effects to ergotamine which is from ergot (Claviceps purpurea). Efforts to use corn smut medicinally like ergot has not worked well because it is weaker. See Herb Blurb below. As a fungus corn smut is a distant relative of Boletus and Agaricus mushrooms. Also, out of 1,000 smut species it is one of two commonly eaten. The other is Ustilago esculenta, which grows on rice stalks in China.

Corn smut is widespread. While native to Central America it now has almost worldwide distribution. It is rare, however, in tropical regions and is not found in New Zealand. Corn smut was first noticed in Australia in 1911 but was eradicated around the beginning of World War II. It reappeared in Australia in 1982.  It’s common in Europe wherever corn is grown. Corn smut is intentionally grown in limited quantities in California, Georgia, Virginia and in nearby Groveland, Florida. In the United States up to 5% of the corn crop can be unintentionally affected with some species of corn more susceptible than others such as sweet corn. A larger problem is when one infected ear is mechanically harvested the inky spores cover many other good ears picked at the same time making them unusable plus the machine needs to be cleaned. Millions have been spent trying to control it.

Raw corn smut

Cooked corn smut

As one might expect there are disagreements on what huitlacoche means exactly.  While authorities agree huitlacoche (week-la-KOH-chay) comes from the Aztecs there are two or more interpretations which are variations on a theme. Some say it means “sleeping excrement” others “raven excrement.” Regardless, you get the idea. As for the Dead Latin name Ustilago (oos-TILL-ah-go) it means “burnt” because of the way the smut  can look as it ages. Maydis (MAY-diss) is the local reference to the corn. Huitlacoche is also written cuitlacoche.

Green Deane’s Itemized Plant Profile: Corn Smut

IDENTIFICATION: Ustilago maydis: Look for large irregular swellings up to 7 inches (20 cm) across on the stems, leaves and ears.  Young galls are silvery-white covered by a thin grayish skin. The gall darkens then ruptures exposing a dark brown, powdery spore mass. Spores are rounded and pale brown, densely covered with small pointed spines.

Chef Rick Bayless

Chef Rick Bayless

TIME OF YEAR:The local corn-growing season.  Rick Bayless, author, chef of Mexican cuisine, owner of Frontera Grill in Chicago says “Pick it when it feels like a pear starting to ripen, when there’s a little give to it. Too firm and it will be bitter. Too late, when the thin skin of the gall breaks if you rub it, and it will taste really muddy.”

ENVIRONMENT: Huitlacoche grows best during times of hot weather in a 78°F to 93°F (25°C–34°C). Prefers nitrogen-rich soil, dry conditions after rain.

METHOD OF PREPARATION: Collected when young and still moist, they are usually cooked like mushrooms. One common simple use is to flavor scrambled eggs. See recipes below.

Huitlacoche Soup

Recipe from Ellen and Tom Duffy

In damp weather corn frequently becomes infected with corn smut–Ustilago maydis–which when fresh occurs as pearly gray globules and ovoids displacing the rows of kernels. They should not be used when old and dried and powdery. At this time the black interior is widely exposed and the gleaming surface gone. It may cause uterine contractions in pregnant women when old and decayed. It is considered a great delicacy in parts of Mexico and here is a soup we have developed. It is delicious with a slight gray color. (There are black spores in the fresh globules also.)

A.

  • 1-1/2 cups (354 ml) milk
  • 3 Tablespoons (44 ml) flour
  • 3 Tablespoons (44 ml) butter
  • 2 Tablespoons (30 ml) Worcestershire sauce
  • 4-6 drops Tabasco sauce

B.

  • 1 cup of huitlacoche (or slightly more)
  • 1 small yellow onion
  • 1 clove garlic
  • 2 Tablespoons (30 ml) bland oil or margarine or ghee
  • 1 cup (354 ml) chicken broth

Whirl together all ingredients in group “A” in a blender or food processor until mixed. Cook slowly, stirring until white sauce thickens. Chop finely all solid ingredients in group “B” and sauté until tender–add the huitlacoche last as it cooks a little quicker. Whirl in blender or food processor with the chicken broth, add to the cream sauce, heat and enjoy.

Ustilago maydis, a new fungal model system for cell biology.

Abstract

The use of fungal model systems, such as Saccharomyces cerevisisae and Schizosaccharomyces pombe, has contributed enormously to our understanding of essential cellular processes in animals. Here, we introduce the corn smut fungus Ustilago maydis as a new model organism for studying cell biological processes. Genome-wide analysis demonstrates that U. maydis is more closely related to humans than to budding yeast, and numerous proteins are shared only by U. maydis and Homo sapiens. Growing evidence suggests that basic principles of long-distance transport, mitosis and motor-based microtubule organization are conserved between U. maydis and humans. The fungus U. maydis, therefore, offers a unique system for the study of certain mammalian processes.

Huitlacoche (Ustilago maydis) as a food source–biology, composition, and production.

Source

Centro de Investigación y de Estudios Avanzados del IPN, Departamento de Biotecnología y Bioquímica, Gto., México.

Abstract

Huitlacoche is the ethnic name applied to the young fruiting bodies (galls) of the fungus Ustilago maydis, which causes common smut of maize (Zea mays L). Biologists and agronomists have historically used U. maydis as a model to study a wide array of genetic, physiological, ecological, and phytopathological phenomena. In Mexico and other Latin American countries, huitlacoche has been used traditionally as human food, being highly regarded as an interesting dish or condiment. The food potential of huitlacoche is described here in terms of its chemical composition, which includes carbohydrates, proteins, fats, vitamins, and minerals. In addition, essential amino acids (especially lysine) and fatty acids (linoleate) are present in huitlacoche in considerable levels, adding to its nutritional attributes. The feasibility of growing U. maydis in submerged agitated culture has yielded a variety of fermentation products, including essential amino acids, proteins, vitamins, and flavorings, among others. Recent interest in developing huitlacoche as a cash crop has come from increasing acceptance by the North American public, who prize it as a new delicacy. However, research efforts are still needed to determine the biological factors involved in the establishment of U. maydis as a pathogen on the maize plant. This review deals with the role of huitlacoche as a food source, implicating the biological components that will determine the development of technologies for large scale production.

Farming Fungus In Florida

By the Organizations of American States

Grown in Groveland, Florida

Grown in Groveland, Florida

FORTY-NINE-YEAR-OLD Roy Burns of Burns Farms Huitlacoche, Groveland, Florida, has something growing in his field that most farmers dread the sight of–corn fungus. In the last six years Burns has almost cornered the U.S. market for this latest ethnic food fad known by its Latin taxonym, ustilago maydis, but more commonly by its Nahuatl name, huitlacoche.

While other farmers fear outbreaks of the crop-killing plague they curse as “corn smut,” Burns hopes to get rich off it. “People think I’m crazy for trying to grow this stuff on purpose,” he says. “But one of these days I’ll get it right and then I’ll be the huitlacoche king.”

Huitlacoche is a delicacy in Mexican cooking, but its availability in the market is an unforeseen accident of the growing season. Rain, temperature, and wind all play a role in making the fungus break out in any given field at any given time. If an outbreak does occur, a farmer in Mexico might lose his corn but can sell his huitlacoche to any number of buyers.

It is not so simple in the U.S., however, where huitlacoche is not as well known as, say, mushrooms–still every bit the fungus as the Mexican variety. But Mexican chefs, cookbook authors, and restaurants north of the border call increasingly for this hard-to-find ingredient. It has even found its way onto menus of many non-Mexican eateries as an exotic garnish. Legend has it that Emperor Maximilian rolled huitlacoche in his crepes, turning it overnight into a rare French treat.

Josefina Howard, owner of New York City’s Rosa Mexicana restaurant on the tony East Side, has done more than anyone to popularize huitlacoche in the U.S., serving up about one hundred pounds a week. “Huitlacoche has a wonderful earthy corn taste–and cooks into the most elegant black color,” she says. “It’s so adaptable, it can go in anything–soup, sauce, ice cream, you name it.”

The Burns farm is located in Florida’s citrus belt within sight of DisneyWorld, but Burns is completely on his own when it comes to growing huitlacoche. He and his brother have been experimenting hit-or-miss to mix and apply fungus spores to individual ears of corn in order to produce a big crop at the right time.

“Our county extension agent doesn’t know the first thing about growing a crop fungus,” says Burns. “All he cares about is eradicating it. And no one on the agricultural trade board will give me the time of day. They all think I’m nuts to be trying to sell corn smut.”

Burns sold almost seven thousand pounds last year, grown on just seven acres of corn. With demand soaring and he the only grower, he plans to push the price past ten dollars per pound on his next crop. That comes to a nifty profit per acre.

But growing huitlacoche presents plenty of pitfalls. El Nino’s torrential rains wiped out all his winter corn, and with it his fungus crop. Timing the harvest is also critical. Picking by hand, ear by ear, requires strict crew control. Getting into the field just a day late means losing this highly perishable crop.

Marketing too can be a problem. If he can’t supply customers in a timely fashion, they threaten to switch to a canned Mexican product, albeit with a far inferior taste. For this reason alone, Burns has many chefs rooting for his success. This year he plans to harvest his summer crop through July and hopes to have enough in the freezer to last until the winter crop comes in October.

Hardy Orange, sometimes in the citrus clan, sometimes not. Photo by Aubree Cherie

Is the Hardy Orange edible? That depends on how hungry you are, or which century you live in.

The Hardy Orange is well-armed with thorns.

A native of China, Hardy Orange (Poncirus trifoliata) aka Trifoliate Orange, was once grown in northern Europe where the fruit rind was candied and dried. As a cold-hardy pseudo- citrus American colonists also grew the Hardy Orange because the fuzzy fruit has pectin which was used in making jams and jellies. The fruit, minus, seeds, was also made into a not-sweet marmalade. In China the bitter fruits were used as seasoning (dried and powdered) and young leaves are occasionally boiled and eaten. Fresh fruit allowed to sit for two weeks after picking yields about 20% juice which can be diluted and made into a drink. The flavor is a cross between lemon and grapefruit. A slice of it is good in a gin-and-tonic. Do note that processing leaves a hard-to-wash off resin on utensils. The University of North Carolina, which I think believes every plant is toxic, lists the Hardy Orange as “poisonous.” It says the fruit can cause “severe stomach pain and nausea, prolonged contact can cause skin irritation.”  But it also says “causes only low toxicity if eaten, skin irritation minor, or lasting only for a few minutes.” The fruit may also have some anti-allergic activity. In Chinese medicine it has been used to treat typhoid, toothache, hemorrhoids, conjunctivitis, colds and itchy skin.

Leaves are arranged in threes.

The Hardy Orange is naturalized in the United States from Pennsylvania south and west to northern Florida and eastern Texas. In recent times Poncirus trifoliata has been used primarily as root stock for citrus along with at least three developed cultivars: Barnes, Rubidioux, and Flying Dragon, the latter of which has curved thorns.  Interestingly while the original species came with the colonists the Flying Dragon was introduced from Japan to the U.S. in 1915 by American botanist Walter Tennyson Swingle (1871-1952). Swingle’s first major job was not far from here in Eustis, Florida, in 1892. He and Dr. Herbert John Webber experimented with citrus and formed the basis of much of what is known about citrus. They created Tangelos including the Minneola and crossed the Poncirus trifoliata with Citrus sinensis to create the Citrange, common in many landscaped gardens.  In 1943 Swingle wrote “The Botany of Citrus and Its Wild Relatives of the Orange Subfamily.” Webber, by the way, was no botanical slouch either. He wrote over 300 research papers and created many cotton species that are still used in the clothes you wear.

Walter Tennyson Swingle

Like many thorn-ladened trees, birds select the Hardy Orange to make their nests in as the two-inch thorns dissuade predatory creatures.  The tree can be used as a natural fence and have often been used to corral livestock. The thorns are sturdy enough to puncture a tire or use as a tooth pick. The wood is extremely is hard and dense, the bark striped with green, stems are triangular. Early spring flowers are popular with bees and butterflies. Deer don’t like it nor rabbits. The aromatic fruit, ripening in the fall,  can also be dried and used in potpourri mix. Fall foilage is butter-yellow.

Herbert John Webber

The Hardy Orange grows to about six feet (sometimes 20 feet!) and starts bearing around 12-years old. They are a common bonsai specimen. It loses its leaves in winter and can be grown in protected areas as far north as Canada. It has been cultivated in China for thousands of years and in Japan since the 8th century. As mentioned above it came to North America in colonial times and was introduced into Australia in the late 1800s. It is also commonly used in Argentina. Hardy Orange prefers low-lime soil.

The botanical name, Poncirus trifoliata, is said  pon-SEER-us try-foh-lee-AY-tuh, some say pon-SIGH-russ. Poncirus is from French meaning a citron. Trifoliata means three leaves.

Green Deane Itemized Plant Profile: Hardy Orange

IDENTIFICATION: Poncirus trifoliata: Tree to 20 feet, leaves alternate, compound, three leaflets, 1 to 2 inches long, may be finely wavy toothed, thickened, petiole winged, shiny dark green, flowers white, cup-shaped, fragrant. Vicious thorns, small fruit. Self-fertile, propagate by planting fresh seeds from ripe fruit. If you are going to store the seeds keep them cool (35-40F for at least 30 days) then warm for 24 hours in warm water. Chilled seeds germinates in two weeks if kept around 70-80F, a month at 60-70F. Poncirus is a monotypic genus with the only member the trifoliata.

TIME OF YEAR: Flowers in early spring, fruit in late fall.

ENVIRONMENT: Not too picky about soil but does not like line-heavy soil, prefers full sun but can tolerate some shade. Likes moist soil but will not tolerated being water logged.

METHOD OF PREPARATION: Fruit as marmalade, dried as seasoning, juice diluted for a drink.

Hardy Orange Marmalade

Adding stick cinnamon is optional

Use 30 to 50 fruit depending upon their size. Wash well.  Cut each one equatorially and twist the halves apart. Squeeze the pulp, seed and what juice there is into a bowl. Remove the seeds. This is helped by adding a little water. You can slice the peelings or leave them whole.

Add the peelings to a jar holding 2.5 cups of water and 1/8 teaspoon of baking soda. Bring to a boil and simmer for 10 minutes. Pour off about 2 cups of the water. Add the juice and pulp and simmer for 10 more minutes. Meanwhile put enough jars (lids and screw-caps) for eight cups of marmalade into a big pot of water and bring them to a boil. Continue to let them boil very gently until the marmalade is ready to can.

Measure 4 cups of sugar then take 1/4 cup of that sugar and mix it with one package of pectin in a small bowl.  In the large bowl add enough water to the juice/pulp mixture to bring the volume to 5.5 cups and put it in a gallon pot for cooking. Add the sugar/pectin mixture from the small bowl and a 1/2 tablespoon of oil. Bring  a full boil stirring constantly as it heats. Then add the rest of the sugar and heat this till it again reaches a full boil. Boil for one more minute only. Turn off the heat and quickly put the marmalade into the sterile jars. Fill each jar to within 1/4 inch of the top, wipe off any marmalade that touches the rim. Set the lid, tighten, then do the next jar. Sealed jars should keep for months.

If you want to reduce the bitterness of the peelings first you can parboil them in as many changes of water as you like until the water is not bitter or of a bitterness of your liking. Cooking will leave a resin on your utensils. Alcohol will remove it quickly.

The effect of an aqueous extract of Poncirus trifoliata (L.) Raf. (Rutaceae) fruits (PTFE) on compound 48/80-induced mortality associated with anaphylaxis was studied in rats. PTFE inhibited compound 48/80-induced anaphylaxis 100% with a dose of 1.6 mg/g body weight (BW) 1 h before or 5 min after injection of compound 48/80. PTFE inhibited compound 48/80-induced anaphylaxis almost 100% with doses above 0.4 mg/g BW intraperitoneally administered. PTFE (1-1000 micrograms/ml) also dose-dependently inhibited the histamine release induced by compound 48/80 (5 micrograms/ml) in rat peritoneal mast cells. The level of cAMP in peritoneal mast cells, when PTFE was added, increased transiently, and significantly increased 53-fold at 10 s compared with that of basal cells. Moreover, PTFE inhibited intracellular calcium release induced by compound 48/80. These results suggest that PTFE has antianaphylactic activity by stabilizing the peritoneal mast cell membrane.

Abstract

Poncirin was isolated from water extract of the fruits of Poncirus trifoliata and metabolized by human intestinal bacteria. The inhibitory effect of poncirin and its metabolites by these bacteria on the growth of Helicobacter pylori (HP) was investigated. Among them, ponciretin (5,7-dihydroxy-4′-methoxyflavanone), the main metabolite most potently inhibited the growth of HP, with a minimum inhibitory concentration (MIC) of 10-20 microg/ml. However, poncirin and its metabolites except ponciretin did not inhibit the growth of HP, nor did they inhibit HP urease.

Anti-inflammatory effect of Poncirus trifoliata fruit through inhibition of NF-?B activation in mast cells

Toxicology in Vitro, Volume 20, Issue 7, October 2006, Pages 1071–1076

Abstract

Mast cell-mediated allergic inflammation is involved in many diseases such as asthma, sinusitis, and rheumatoid arthritis. Mast cells induce synthesis and production of pro-inflammatory cytokines including tumor necrosis factor (TNF)-? and interleukin (IL)-6 with immune regulatory properties. We investigated the effect of the fruits of Poncirus trifoliata (L.) Raf (Rutaceae) (FPT) on expression of pro-inflammatory cytokines by activated human mast cell line, HMC-1. FPT dose dependently decreased the gene expression and production of TNF-? and IL-6 on phorbol 12-myristate 13-acetate (PMA) and calcium ionophore A23187-stimulated HMC-1 cells. In addition, FPT attenuated PMA and A23187-induced activation of NF-?B indicated by inhibition of degradation of I?B?, nuclear translocation of NF-?B, NF-?B/DNA binding, and NF-?B-dependent gene reporter assay. Our in vitro studies provide evidence that FPT might contribute to the treatment of mast cell-derived allergic inflammatory diseases.

Poncirus trifoliata fruit induces apoptosis in human promyelocytic leukemia cells

Volume 340, Issues 1–2, February 2004, Pages 179–185

Abstract

Background: Substances inducing apoptosis have shown efficacy in the treatment of cancers. Poncirus trifoliata (L.) Raf. (Rutaceae) fruits (PTF) has been used for the treatment of various cancers among Korean Oriental Medical doctors. Methods: PTF-induced cytotoxicity of human leukemia HL-60 cells was monitored by the MTT assay. The apoptosis was determined by (a) apoptotic morphology in microscopy; (b) DNA fragmentation in electrophoresis and FACS analysis; and (c) activation of caspase-3 and poly-ADP-ribose polymerase (PARP) cleavage assay. Results: The cytotoxic activity of PTF in HL-60 cells was increased in a concentration- and time-dependent manner. PTF caused the cell shrinkage, cell membrane blebbing, apoptotic body and DNA fragmentation. PTF-induced apoptosis is accompanied by the activation of caspase-3 and the specific proteolytic cleavage of PARP. However, PTF did not show cytotoxicity in normal peripheral blood mononuclear cells. Conclusions: Our novel finding provides evidence that PTF could be a candidate as an anti-leukemic agent through apoptosis of cancer cells.

A flower is a flower is a flower. But in Victorian England, one of the most self-repressed societies in modern times, the practice of using flowers to communicate was developed. Over time a bouquet could visually speak of feelings and thoughts one could not or would not say in person to another particularly one you might be in love with. Of course anyone else familiar with the floral code could also know what the message was, or maybe even alter it…. sounds like a nice plot for a Victorian novel…

Several segments of society developed this language of flowers. The list below is probably incomplete and opinions may vary on this or that particular flower. They are not all edible by any means. If you want to read about edible flowers, click here for edible cultivated flowers, here for edible wild flowers.

And while we may say “how quaint” of the Victorians to put such meaning into individual species a shadow of that practice is still with us with certain flowers for certain occasions or certain flowers not used on certain occasionals such as never send carnations to a funeral but do send red roses on Valentine’s Day. Oddly the practice of sending a dozen roses on Valentine’s Day is only about a century old. The previous flower of choice was violets, which are still left on Chopin’s gave in Paris even in winter. The day Chopin was buried one of his students, Jane Sterling, bought all the violets she could find in Paris to cover is grave thus starting a tradition.  Here is the Language of Flowers.
