Harvest pears when they are mature but still hard. Ripen the pears at room temperature for the best quality. Some pears need chilling to ripen fully like Forelle and Packham's Triumph.
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.
