Butterfly bush-friend of foe?
Someone gave me one for my birthday-a beatiful dark purple one. Havn't planted it yet, and I heard somewhere that they are considered to be invasive. Any truth to this? Will it escape from my 1/10 acre in the middle of town? I was really curious to see what kind of butterflies I might get with this, but I don't want to be part of the problem. Advice please! :)
