Common Pear Overview
The pear is a medium-sized tree or shrub, reaching 10–17 m tall, often with a tall, narrow crown. The alternate leaves are simple, glossy green on some species, and densely silvery-hairy in some others. The leaf shape varies from broad oval to narrow lance-shaped. Most pears are deciduous, but one or two species in southeast Asia are evergreen. Most are cold-hardy, withstanding temperatures between −25 °C and −40 °C in winter, except for the evergreen species, which only tolerate temperatures down to about −15 °C. The flowers are white, rarely tinted yellow or pink, and have five petals. The pear fruit is a pome, in cultivated forms they grow up to 18 cm long and 8 cm broad; the shape varies in most species from oblate or globose, to the classic pyriform 'pear-shape' of the European pear.
