Well, I have grown them since I moved down to GA over four years ago. And I find volunteers every spring. Now, that said, the seed I have is a very old perennial unknown variety from my mother. I will be starting some seeds in a few weeks in paper pots. I like to plant in paper pots because they develop a long root quickly and it gets disturbed less that way.
If you want some seeds I have lots. SASE cause I am not good anymore about mailing things otherwise. Tree mail me if you want some. I'll see if I can find a photo.
