There are many different pawpaw's. This one is only a shrub. Gets max. 4'. There is precious little info. about this particular one. It is native to Fl., so, Ga., & rarely so. Al. Well, here; this is the info. on it. I had to hunt high & low to get the info.
Slimleaf Pawpaw (Asimina longifolia)
It is a pretty shrub. I like it & am going to harvest seeds when they ripen. I'm toying with the idea of trying to transplant one but it may be too late as they are all getting pretty good size.
