Callery Pear
Pyrus calleryana
Description
CAUTION: INVASIVE TENDENCIES. Pyrus calleryana, or callery pear, is not recommended to plant, due to invasive tendencies. It is native to China, Japan, Korea, Taiwan, and Vietnam. Callery pear is short-lived and can be quite thorny. It prefers full sun, and well-draining, loamy soil, with a pH between 6 and 8.5. Pruning should be done as needed in winter to improve the tree's strength and structure as this species can be prone to branch breakage in storms. An alternative option is the Amelanchier or Cercis canadensis.
