Additional Notes

Comments

Pyrus calleryana is a widely planted ornamental, popular for its showy (but malodorous) white spring blossoms and red, maroon, burgundy, or yellow fall foliage. However, it has become a serious urban and suburban weed in eastern Kansas in the past 10 years. The Bradford pear is the first of what are now many cultivars of the Callery pear.
