This particular butterfly bush is an original one that I brought from Connecticut. What's particularly amazing is that I grew it from seed thinking it was a flower and it became three intertwined bushes that I had to separate. Today we have a couple other varieties, but this one came from a seed packet not a nursery. So its possible to grow buddlleja from seed, but plan for the space accordingly. They get a large root system. Then enjoy them through fall when the last of the butterflies drunkenly laze around them.
