CSSA sells San. seed off and on when they get them. .50 for 5 seeds. I will have a few soon also . I do not sell them. The last batch went to kenneth quinn. He is very successful having them come up. My understanding is that they are slow to mature, meaning into the 4" pot size. I do have a few seeds left that I will mail. Norma Lewis where it is 100F today. But why can't I grow S . hahnii?
