Do butterfly bushes come back every year?

Butterfly bushes are perennial plants that die back to the ground every winter. They then send out new growth from the roots in the spring. You can prune them either in the late fall or in the early spring before the new growth starts. It is best to prune them back to about 12 inches from the ground.

Why you should never plant a butterfly bush?

Each Butterfly Bush produces over 100,000 seeds, and they are distributed in the wind, so even though you may not see seedlings popping up in your garden, your Butterfly Bush is probably responsible for spreading devastation in natural areas like stream banks and disturbed industrial sites.
