Tnanks so much for letting me know what you found out.** :)Once your butterfly bush goes to seed you'll have lots more volunteers.* It's been listed as an invasive or potential invasive in many states.* I deadhead mine to keep it blooming, but I try and cut off all the seed heads at the end of the season so it doesn't spread around.* I'm considering adding it to the compost pile.** :(
