Plant Species of the genus Pyracantha

Information about this genus
Name: Pyracantha
Cultivation: CULTIVATION: Most are fairly adaptable shrubs tolerating exposed sites in full sun. They perform best in a fertile well-drained soil. Pruning is not essential but may be helpful to control size; hedges can be pruned early to mid-summer. Watch for fireblight, scab and wilt problems. Propagate from seed or cuttings.
Description: This small genus in the pome subfamily of the rose family consists of 9 species of mostly spiny shrubs, the majority from eastern Asia, one from southeast Europe. The name is derived from the Greek pyr, meaning ?fire?, and akanthos, meaning ?thorn??hence the common name firethorn. They have simple leaves that are often toothed on the margins, and whitish flowers in corymbs are produced at the ends of branches. The flowers are followed by attractive masses of fruit which persist into winter. These fruits are usually small red, orange or yellow berries, edible but without taste. The seeds may cause stomach complaints. Most species occur in scrub and woodland areas and perform best in cool, moist climates where they are useful landscape subjects for the shrubbery or used as an espalier or for hedging. There are many cultivars and hybrids within the genus. Pyracantha species can naturalize in favorable areas.
