In this Daily Herald article, David Horvath from Davey's Lake Bluff office talks about the Bradford pear and explains why its invasive behavior led to it being banned in Illinois.

A close shot of white flowers in a tree.Every April, a different kind of blizzard sweeps across Chicago-area neighborhoods. White blossoms line parkways in Naperville, commercial strips in Schaumburg, and front yards in Arlington Heights. It's one of the most recognizable signs of spring and as of last fall, officially an invasive weed in Illinois. 

But the beautiful Callery pear turned out to be an environmental Trojan horse. Also sold as Bradford pear, it has quickly become a nuisance. As of October 2025, it has been added to Illinois' Exotic Weed Act, making it illegal to buy, sell, distribute, or plant in the state. Nurseries have been given a grace period to phase out existing stock, with the full sales ban taking effect Jan. 1, 2028. 

Don't worry. If you have a pear in the ground, you aren't required to remove it. But this is a good time to take stock and assess what's next.
