Other names: Bradford Pear
Initially, the cultivated variety of P. calleryana produced sterile fruit. As other cultivars were introduced in the trade to minimize limb breakage, they produced viable fruit, and these trees are now invading forests and natural areas.
Some naturalized populations may be hybrids of various cultivars of P. calleryana, or hybrids between this species and other Pyrus. The largish, mealy fruit is mainly consumed by European Starlings (Sturnus vulgaris) or other larger birds, including gulls.
Fruit ripening dates: Late September onward
