Distribution en: Temp. Eurasia to Indo-China, NW. Africa
Description en: Genus of about 30 species of upright, mainly deciduous trees and shrubs, found in woodland, in rocky places, and on hillsides in Europe, W. to E. Asia, and N. Africa. They are grown for their habit, flowers, and fruits. The leaves are alternate, entire or very rarely lobed, ovate to oblong, elliptic, or oval, the margins often with forward-pointing teeth; some have good autumn colour. The 5-petalled, saucer- to bowl-shaped flowers, borne in umbel-like racemes, are white, occasionally pink, and usually have red anthers. The fruits are spherical to typically pear-shaped; numerous cultivars have been bred specifically for the production of culinary and dessert pears. Ornamental pears are best grown as specimen trees on a lawn; the smaller ones such as P salicifolia ’Pendula’, and those of narrow habit, such as P. calleryana ’Chanticleer’, are particularly suitable for growing in a small garden.
Hardiness en: Fully hardy.
