Callery Pear (Pyrus calleryana)

Callery pear (Pyrus calleryana) has completely infested at least one local area. You're probably familiar with the Bradford Pear cultivar, one of the most widely planted (and overused) landscaping trees in the U.S. The ones growing here are the result of the Bradford pear seeding out and is different than the cultivar, with viscious thorns and it suckers profusely. This is probably the first tree to bloom in this area and I was surprised to see some of them bloom again in the Fall. The fruits are about the size of a pea and are inedible but birds do like them.
