I have some seeds from my garden if anyone is interested.
I have Globe Thistle (light purpleish-blue blooms), Knautia Macedonica (Burgundy blooms) and Columbine (not sure what colors these seed are - you can check out my earlier posts about the Columbine and get an idea of what you might get).
If you would be interested in trying these out, then comment on this post with your name and address and I'll send some to you.
I am not guaranteeing that they will grow. I think that would be up to you. :)
If they DO grow and bloom, please send me a photo.
