I recently harvested the seeds from my many Columbine plants. I'd like to plant the seeds in some other places on my property. Should I drop the seeds now or wait until the Spring? I'd also like to reseed the existing plants as well. When is the best time to do it? Seems the plants themselves are dropping them naturally now, but I'd like to give the seeds the best chance for nice growth next year, which is why I'm thinking after the winter would be better. Thoughts?
