Pyrus calleryana ‘Jack’

Callery Pear
Rosaceae
Deciduous, Trees, Flowers

PYRUS

Ornamental pears are grown for their profuse late-winter or early-spring show of white flowers and their lustrous leaves. Not at their best in shallow soils, they’re otherwise unfussy, even growing well in heavy clay. Most are subject to fireblight. Fruiting pears are described under Pear, Asian and Pear, European.

Pyrus calleryana

This deciduous tree grows to 50 ft. tall and wide, with a strong horizontal branching pattern; young growth is thorny. Broadly oval, scallop-edged, leathery, 1/2–3-in.-long leaves are glossy dark green, turning rich purplish red in fall. Blooms very early; late freezes may destroy flower crop. Very small, round, inedible fruit. Less susceptible to fireblight than most pears.
