Botanical Name:Vaccinium
Family:Ericaceae
Kingdom: Plantae
Order: Ericales
Genus: Vaccinium
Section: Cyanococcus

Habitat:The genus Vaccinium has a circumpolar distribution with species in North America, Europe and Asia.

Many commercially sold species whose English common names include “blueberry” are currently classified in section Cyanococcus of the genus Vaccinium and come predominantly from North America. Several other plants of the genus Vaccinium also produce blue berries such as the predominantly European bilberry (Vaccinium myrtillus), which in many languages has a name that means “blueberry” in English.

Many North American native species of blueberries are now also commercially grown in the Southern Hemisphere in Australia, New Zealand and South American countries.

Description:
Blueberries are flowering plants of the genus Vaccinium with dark-blue, -purple or black berries. Species in the section Cyanococcus are the most common fruits sold as “blueberries” and are mainly native to North America.  They are usually erect but sometimes prostrate shrubs varying in size from 10 cm tall to 4 m tall. In commercial blueberry production, smaller species are known as “lowbush blueberries” (synonymous with “wild”), and the larger species as “highbush blueberries”. The leaves can be either deciduous or evergreen, ovate to lanceolate, and from 1–8 cm long and 0.5–3.5 cm broad. The flowers are bell-shaped, white, pale pink or red, sometimes tinged greenish.

The fruit is a false berry 5–16 mm diameter with a flared crown at the end; they are pale greenish at first, then reddish-purple, and finally blue on ripening. They have a sweet taste when mature, with variable acidity. Blueberry bushes typically bear fruit from May through June though fruiting times are affected by local conditions such as altitude and latitude.

The Chippewa Indians used the flowers to treat psychosis. The fruit contains anthocyanosides. These chemical compounds are very powerful antioxidants that are very effective in the prevention of heart disease and cancer.

Some other blue-fruited species of Vaccinium:

Vaccinium koreanum
Vaccinium myrsinites (Evergreen Blueberry)
Vaccinium myrtillus (Bilberry)

Cultivation:
Blueberries may be cultivated, or they may be picked from semi-wild or wild bushes. In North America, the most common cultivated species is V. corymbosum, the Northern highbush blueberry. Hybrids of this with other Vaccinium species adapted to southern U.S. climates are known collectively as Southern highbush blueberries.

Blueberry flowersSo-called “wild” (lowbush) blueberries, smaller than cultivated highbush ones, are prized for their intense color. The lowbush blueberry, V. angustifolium, is found from the Atlantic provinces westward to Quebec and southward to Michigan and West Virginia. In some areas, it produces natural blueberry barrens, where it is the dominant species covering large areas. Several First Nations communities in Ontario are involved in harvesting wild blueberries. Lowbush species are fire-tolerant and blueberry production often increases following a forest fire as the plants regenerate rapidly and benefit from removal of competing vegetation. Wild has been adopted as a marketing term for harvests of managed native stands of low-bush blueberries. The bushes are not planted or genetically manipulated, but they are pruned or burned over every two years, and pests are “managed”.

There are numerous highbush cultivars of blueberries, each of which have a unique and diverse flavor. The most important blueberry breeding program has been the USDA-ARS breeding program based at Beltsville, Maryland, and Chatsworth, New Jersey. This program began when Frederick Coville of the USDA-ARS collaborated with Elizabeth Coleman White of New Jersey. In the early part of the 20th Century, White offered wild pickers cash for large-fruited blueberry plants. Rubel, one such wild blueberry cultivar, is the origin of many of the current hybrid cultivars.

Rabbiteye Blueberry (V. virgatum, syn. V. ashei) is a southern type of blueberry produced from the Carolinas to the Gulf Coast states.

Other important species in North America include V. pallidum, the Hillside or Dryland Blueberry. It is native to the eastern U.S., and common in the Appalachians and the Piedmont of the Southeast. Sparkleberry, V. arboreum, is a common wild species on sandy soils in the southeastern U.S. Its fruits are important to wildlife, and the flowers important to beekeepers.

Uses:
Blueberries are sold fresh or processed as individually quick frozen (IQF) fruit, purée, juice, or dried or infused berries which in turn may be used in a variety of consumer goods such as jellies, jams, pies, muffins, snack foods, and cereals.

Blueberry jam is made from blueberries, sugar, water, and fruit pectin. Premium blueberry jam, usually made from wild blueberries, is common in Maine, Ontario, Quebec, and British Columbia.

Nutrients and phytochemicals:
Blueberries have a diverse range of micronutrients, with notably high levels (relative to respective Dietary Reference Intakes) of the essential dietary mineral manganese, vitamin B6, vitamin C, vitamin K and dietary fiber (table). One serving provides a relatively low glycemic load score of 4 out of 100 per day.

Especially in wild species, blueberries contain anthocyanins, other antioxidant pigments and various phytochemicals possibly having a role in reducing risks of some diseases, including inflammation and certain cancers.

Medicinal Uses:
Blueberries have become highly popularized by their new-found medicinal properties. However, this native American fruit has been in use for thousands of years as part of the native Indian diet. The blueberry is not only sweet and delicious, but is rich in Vitamin C, manganese, and dietary fiber. being in the same fruit family as cranberry, the blueberry is equally high in antioxidants. The high grocery store price of blueberries is a great reason to grow your own bushes. Blueberry plants are easy to grow and have a long productive life. Just a few bushes would provide adequate berries for a small family. There are many blueberry varieties, so Willis Orchard Company has made it easy for you by offering only the best varieties. Choose any of our varieties and you will be pleased with abundant crops of delicious, healthy blueberries.

Researchers have shown that blueberry anthocyanins, proanthocyanidins, resveratrol, flavonols, and tannins inhibit mechanisms of cancer cell development and inflammation in vitro. Similar to red grape, some blueberry species contain in their skins significant levels of resveratrol, a phytochemical.

Although most studies below were conducted using the highbush cultivar of blueberries (V. corymbosum), content of polyphenol antioxidants and anthocyanins in lowbush (wild) blueberries (V. angustifolium) exceeds values found in highbush species.

At a 2007 symposium on berry health benefits were reports showing consumption of blueberries (and similar berry fruits including cranberries) may alleviate the cognitive decline occurring in Alzheimer’s disease and other conditions of aging.

Feeding blueberries to animals lowers brain damage in experimental stroke. Research at Rutgers  has also shown that blueberries may help prevent urinary tract infections.

Other animal studies found that blueberry consumption lowered cholesterol and total blood lipid levels, possibly affecting symptoms of heart disease. Additional research showed that blueberry consumption in rats altered glycosaminoglycans which are vascular cell components affecting control of blood pressure.

Blueberry has been used in connection with the following conditions (refer to the individual health concern for complete information):
Common cold/sore throat,  Diarrhea and Urinary tract infection

Bilberry is a name given to several species of low-growing shrubs in the genus Vaccinium (family Ericaceae) that bear tasty fruits. The species most often referred to is Vaccinium myrtillus L., also known as blaeberry, whortleberry, whinberry (or winberry), myrtle blueberry, fraughan, and probably other names regionally. They were called black-hearts in 19th century southern England, according to Thomas Hardy‘s 1878 novel, The Return of the Native, (pg. 311, Oxford World’s Classics edition).
Bilberry fruitThe word bilberry is also sometimes used in the common names of other species of the genus, including Vaccinium uliginosum L. (bog bilberry, bog blueberry, bog whortleberry, bog huckleberry, northern bilberry), Vaccinium caespitosum Michx. (dwarf bilberry), Vaccinium deliciosum Piper (Cascade bilberry), Vaccinium membranaceum (mountain bilberry, black mountain huckleberry, black huckleberry, twin-leaved huckleberry), and Vaccinium ovalifolium (oval-leafed blueberry, oval-leaved bilberry, mountain blueberry, high-bush blueberry).

Bilberries are found in damp, acidic soils throughout the temperate and subarctic regions of the world. They are closely related to North American wild and cultivated blueberries and huckleberries in the genus Vaccinium. The easiest way to distinguish the bilberry is that it produces single or pairs of berries on the bush instead of clusters like the blueberry. Bilberry is used as a food plant by the larvae of some Lepidoptera species – see list of Lepidoptera which feed on Vaccinium.

Bilberries are rarely cultivated but fruits are sometimes collected from wild plants growing on publicly accessible lands, notably in Fennoscandia, Scotland, Ireland and Poland. Notice that in Fennoscandia, it is an everyman’s right to collect bilberries, irrespective of land ownership. In Ireland the fruit is known as fraughan in English, from the Irish fraochán, and is traditionally gathered on the last Sunday in July, known as Fraughan Sunday.

Confusion between bilberries and American blueberries:
Since many people refer to “blueberries”, no matter if they mean the bilberry (European blueberry) Vaccinium myrtillus or the American blueberries, there is a lot of confusion about the two closely similar fruits. One can distinguish bilberries from their American counterpart by the following differences:
*bilberries have dark red, strongly fragrant flesh and red juice that turns blue in basic environments: blueberries have white or translucent, mildly fragrant flesh

*bilberries grow on low bushes with solitary fruits, and are found wild in heathland in the Northern Hemisphere; blueberries grow on large bushes with the fruit in bunches
bilberries are wild plants while blueberries are cultivated and widely available commercially

*cultivated blueberries often come from hybrid cultivars, developed about 100 years ago by agricultural specialists, most prominently by Elizabeth Coleman White, to meet growing consumer demand; since they are bigger, the bushes grow taller, and are easier to harvest

*bilberry fruit will stain hands, teeth and tongue deep blue or purple while eating; it was used as a dye for food and clothes: blueberries have flesh of a less intense colour, thus less staining

*when cooked as a dessert, bilberries have a much stronger, more tart flavour and a rougher texture than blueberries

Adding to the confusion is the fact there are also wild American blueberry varieties, sold in stores mainly in the USA and Canada. These are uncommon outside of Northern America. Even more confusion is due to the huckleberry name, which originates from English dialectal names ‘hurtleberry’ and ‘whortleberry’ for the bilberry.

Edible Uses:   The fruits can be eaten fresh, but are more usually made into jams, fools, juices or pies. In France they are used as a base for liqueurs and are a popular flavouring for sorbets and other desserts. In Brittany they are often used as a flavouring for crêpes, and in the Vosges and the Massif Central bilberry tart (tarte aux myrtilles) is the most traditional dessert.

Constituents:—Quinic acid is found in the leaves, and a little tannin. Triturated with water they yield a liquid which, filtered and assayed with sulphate of iron, becomes a beautiful green, first of all transparent, then giving a green precipitate. The fruits contain sugar, etc.

Mrdicinal Uses:—The leaves can be used in the same way as those of UvaUrsi. The fruits are astringent, and are especially valuable in diarrhoea and dysentery, in the form of syrup. The ancients used them largely, and Dioscorides spoke highly of them. They are also used for discharges, and as antigalactagogues. A decoction of the leaves or bark of the root may be used as a local application to ulcers, and in ulceration of the mouth and throat.

The fruit is helpful in scurvy and urinary complaints, and when bruised with the roots and steeped in gin has diuretic properties valuable in dropsy and gravel. A tea made of the leaves is also a remedy for diabetes if taken for a prolonged period.

Bilberry is often said to improve night vision, and the story is told of RAF pilots in World War II using bilberry for that purpose. A recent study by the U.S. Navy found no effect, however, and the origins of the RAF story are unclear; it does not appear to be well known in the RAF itself.. Studies have shown that bilberry can reduce or reverse effects of degenerative eye disorders such as macular degeneration. The overall therapeutic use of bilberry is still clinically unproven.

Bilberry is primarily used for eye conditions and to strengthen blood vessels. During World War II, British Royal Air Force pilots reportedly found that eating bilberry jam just before a mission improved their night vision which prompted researchers to investigate bilberry’s properties.

Bilberry is also used for glaucoma, macular degeneration, diabetic retinopathy and cataracts.

The anthocyanins in bilberry may strengthen the walls of blood vessels, reduce inflammation and stabilize tissues containing collagen, such as cartilage, tendons and ligaments. Grape seed contains similar substances, however, bilberry’s anthocyanins are thought to have particular benefits for the eye.

Because bilberry is thought to strengthen blood vessels, it’s sometimes taken orally for varicose veins and hemorrhoids.
It may have other beneficial effects on capillaries due to the strong antioxidant properties of its anthocyanidin flavonoids.

The leaves have historically been used to treat gastrointestinal ailments, applied topically or made into infusions. The effects claimed have not been reproduced in the laboratory, however.

Bilberries were also collected at Lughnassadh, the first traditional harvest festival of the year, as celebrated by the Gaelic people. The crop of billberries was said to indicate how well the rest of the crops would fare in their harvests later in the year.
