A couple questions regarding S. rubra.
Are all the Georgia S. rubras "ancestral" type rubras, or are there other rubra subspecies in Georgia?
Are there anthocyanin-free populations of all the rubra supspecies that been found, propagated, and distributed? I am just curious on this. I know of jonesii and gulfensis, and according to ICPS website there may be antho-free of the ancestral population. How about "regular old" rubra rubra and alabamensis?
Do any of you find that the rubras like different conditions from other Sarrs in cultivation? I have grown them from seed at different times, and the seedlings behave normally, albeit a bit slow. However, larger plants don't seem to do as well in the large, undrained plastic pots that I very successfully grow all my other Sarrs in. (Note, I am in NJ, and have a shorter growing season than many here. The pots go into an unheated garage in winter). Maybe I need to change something for them(?).
