Bradford Pears (Pyrus calleryana 'Bradford') are opportunistic trees which easily
grow in disturbed areas. Some places where they invade quite easily are the areas between highways, often adjacent
to a storm water pond. From here, they can continue to produce fruit, which is eaten and dispersed by birds to
other areas.

The Bradford Pears are in full bloom with white flowers. No one planted them there - they just sprung up. Photo by Christa Partain, taken 4/15/2005, in one section of the "clover" of the intersection of Montrose Road and I-270 in Montgomery County.
