Beware the Bradford Pear Tree!

Spring is in the air and so is the white flowering Bradford pear (Pyrus calleryana). You have probably seen tons of them in the Washington DC metro area. Right now in March, they are really pretty with so many small white flowers – like giant puffs of white clouds. But then you begin to see them everywhere: along the highway, in vacated lots, and in every industrial park – like weeds. The Bradford pear was originally thought to be a sterile tree. As new cultivars were created, the cultivars were able to cross pollinate, resulting in small “pears” favored by birds (thus spreading the seed). As time has gone by and the trees have matured, we have learned that they are structurally weak. They develop such a steep V-shaped branching structure, they can easily split in half. Recently, I learned another reason to not plant these weeds.

Last week, when I picked up the kids from school, they complaining of a foul, fish-like odor. I said it was probably the fresh mulch the landscapers applied on the school grounds but they said no, it was the white-flowering trees at their school. I pulled down a branch and sniffed. Sure enough, it smelled like fish! I never knew that about Bradford pears – just another reason not to plant them.

One response to “Beware the Bradford Pear Tree!

  1. Yet some authorities suggest using the BP trunks to graft more productive pear cultivars onto. To graft or not to graft, that is the question. (With apologies to William S.). 😛
