Author's Notes
I remember the first time I saw up close and personal the Butterfly Bush. It was on a tour of Piccadilly Farms in Georgia. A large plant 6-8 by 6-8 and was covered with Flutterbys (Butterfly's). Melinda Meyers in her book wrote she had Butterfly Bushes living for over 5 years (zone #5)
