I found some seeds from a few years ago (3-4) for Phlox Isabellina. It is very hard to find now for some reason. A web site says they only last about two years. Mine were kept in a cool dry basement in their own original envelope. I know someone is going to say 'try it and find out'. Of course that is what i am going to do. But I am also wondering if anyone else has had success germinating annual phlox seeds that are older than 'a couple' years?
As they are rare and hard to find I am really hoping to get them going and save the seeds.
