How Can I Harvest Seed From My Butterfly Bushes?

bonechickchris(7A/6B NJ 08731)August 20, 2008

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

Hi Bonechickchris,

Butterfly bush seeds is one that can be found in the FAQ here.

I'm not sure if they would cross, or if they come true from seed. Maybe someone else here can answer that or you might try asking at The Growing From Seed Forum, or Winter Sowing.

collecting Butterfly Bush ~ Buddleia seeds It takes a long time for the seed pod to brown and split...way into the fall here. If picked b4 they split, they may end up not splitting at all. The seeds are very tiny.

Definitely, the plants cross-pollinate. You'll get quite a mixed batch with your saved seeds. Many plants will bloom their first year, so you don't have to wait too long to find out what color they are.

I've read that it's easy to root cuttings of buddleia, which would guarantee the color you want. I haven't tried this yet. I have started some seeds by wintersowing. Last year's seedlings were planted out in June or July. Some bloomed last year, and all are blooming or will bloom this year.

There has never been a need for me to collect seeds as they seem to volunteer themselves everywhere. I have read that cuttings are the best to make sure you get the colors that you want. My whites and purples have cross-pollinated and the volunteers are a weak lavender that wasn't what I wanted.
