I have a nice batch of shiny black columbine seed from my plants saved to winter sow next Feb. Now I'm wondering if they are good to sow. These columbines were mixed colors, and I've long since thrown out the packet. They would most probably be hybrids, right? What can I expect to get from the seed? Would it be 25% of each parent, and 50% of the hybrid? Or is that too simple?
