This past spring I planted 2 butterfly bushes in large pots, I knew they would not survive here in the ground, but I wanted to see more butterflies, they only cost me $3.99 each in 5 inch pots. They grew just fine, I had lots of bloom on both and it sure attracted lots of bees, moths and butterflies. I cut them way back and stored them under the deck for the winter close to the foundation and piled lots of leaves on top, I am anxious to see if they survived.
