How Can I Harvest Seed From My Butterfly Bushes?
HI there! Could someone tell me how to collect/harvest seed from Butterfly Bushes? I have several and thought It would be neat to collect seed. Are there seeds to collect from every dead head, or do they only seed in the fall? I really do not know much about them. Oh, on another topic, does anyone know if the seeds cross polinate to affect the color of the new seed. Example, I have a bi-color planted not too far away from a white, will my seeds retain the color of their parent or will it vary, or does it not matter?
Thanks again for your help! Christy
