Craven Crab is, in my understanding, a very regional selection. First saw it mentioned by James Lawson, in his nursery catalog, indicating that he’d been given it by Mr. Craven - hence the name.
I’d thought Mr. Lawson was long-gone, but saw, within the last year or so, photo evidence of some NAFEX members visiting him there at Ball Ground, GA… so he may still be among the living.
I purchased scions of Craven Crab from Joyce Neighbors just before she passed her collection of old Southern apples off to the SeedSavers organization… but the tree that resulted from grafting those scions produces a fairly large red apple that ripens in June here in KY. I’m pretty sure that it’s NOT Craven…
