I started these butterfly bushes from seed this year and they are going to bloom. I knew that they grew quickly because we have several of them already growing but they were bought as all ready growing plants. I never thought they would grow this fast from seed.
Our other butterfly bushes are sterile, so they won't grow from seed. I don't know if our winter in zone 5b (central Indiana) will be cold enough to stop them from growing from the seeds they drop. The area they are in is a butterfly garden, so I don't care if they go to seed or not. I know that thy are invasive in some states but I don't know if they are where I am.
Has anyone had a problem with them?
