If you hurry there is someone on the seed exchange with columbine.

I'll have a whole bunch of columbine seeds in the next couple of weeks. Mostly the natives (red and yellow), but some purples and purple and white doubles. They come up very easily in good garden soil without mulch. They usually bloom the following year. Columbines don't last for more than a couple of years, but they just keep migrating throughout my garden. It's really fun waiting to see what color the new plants will be.

Let me know if you want any seeds.
