Are wild ornamental pears growing in your area?


Ornamental Pear webpage

Seedlings of ornamental pears (like Bradford, Aristocrat, etc.) have escaped cultivation in parts of the central U.S., and are rapidly becoming abundant and invasive to open woods, pastures and prairies in many areas.  If you are seeing this where you live,  please let me know approximately how many--

     * less than 10 trees

     * 10-50 trees

     *  over 50 trees

and in what habitat and county/state you have seen them.

Please e-mail me at

Thank you very much!!
