Q: On your website you write that butterfly bush is a good plant to attract butterflies. While that is true, the Georgia Department of Agriculture says butterfly bush is showing signs of becoming invasive.

A: I know that other states have declared butterfly bush, Buddleia davidii, to be invasive but the Georgia Exotic Pest Plant Council (www.gaeppc.org/list) does not list it as being problematic at this time. I’ll take their word for it but I note that several new butterfly bush hybrids are described as sterile. You could plant them instead.
