Common Name: Callery Pear
Scientific Name: Pyrus calleryana Dcne.
Origin: China, Korea, Japan, Taiwan and Vietnam.
Callery pear trees grow as tall as 50 feet, 30 feet wide. Callery pears are deciduous with dark, shiny, leathery, small round-toothed leaves. They have purple hues in the fall. Pears flower in the early spring with five white petals. Fruits mature in the fall as small, hard, brown balls.
Cellary pear grows in full sunlight or some shade. They can deal with both occasionally wet and drought ridden soil. Callery can tolerate urban environments with poor soil.
They establish themselves while displacing native understory vegetation with the dense canopy that creates too much shade. Patches are easily created because they reproduce rapidly by spreading a large quantity of seeds. There are no natural suppressors or controls of callery pear growth. This tree uproots or falls apart easily with wind glaze and snow events.
Stopping the planting of the Callery pear, as well as pulling seedlings and cutting down trees is some management tactics.
