Description

Pyracantha coccinea, the scarlet firethorn is the European species of firethorn or red firethorn that has been cultivated in gardens since the late 16th century. The tree has small white flowers. It produces small, bright red berries. Its leaves are slightly toothed and grow opposite to one another. The fruit is bitter and astringent, making it inedible when raw. The fruit can be cooked to make jellies, jams, sauces and marmalade. It ranges from southern Europe to western Asia. It has been introduced to North America and cultivated there as an ornamental plant since the 18th century. In England, since the late 18th century, it has been used to cover unsightly walls. Pyracantha (from Greek pyr "fire" and akanthos "thorn", hence firethorn) is a genus of large, thorny evergreen shrubs in the family Rosaceae, with common names firethorn or pyracantha. They are native to an area extending from Southwest Europe east to Southeast Asia. They resemble and are related to Cotoneaster, but have serrated leaf margins and numerous thorns (Cotoneaster is thornless). The plants reach up to 4.5 m (15 ft) tall. Leaves are small and oval. The seven species have small white flowers which are 5-merous and many stamened. Fruit are either red, orange, or yellow pomes. The flowers are produced during late spring and early summer; the fruit developes in late summer, and mature in late autumn. The fruit of Pyracantha are classified as pomes. The pulp is safe for human consumption, but it is insipid, and the seeds are mildly poisonous as they contain cyanogenic glycosides (as do apples, plums, cherries, and almonds). Seeds that are chewed and crushed while raw will release cyanogenic glycosides, and can cause mild gastro-intestinal problems when eaten in large enough quantities. The fruit can be made into jelly. The fruits persist significantly into winter which makes them a valuable bird food. A large number of fossil fruits of †Pyracantha acuticarpa have been described from middle Miocene strata of the Fasterholt area near Silkeborg in Central Jutland, Denmark. Pyracantha is a member of the Rose family, and includes seven species. The genus was defined by 19th century botanist Max Joseph Roemer.
