Tony,
Centennial is hard to beat for a sweet crab; haven’t tasted Chestnut, but it always gets rave reviews.
Bill,
I got Craven crab scions from Joyce just before she passed her collection off to SeedSavers. I’m convinced that what she sent is not Craven…it’s a medium-size apple with red skin and mealy flesh, ripe in early summer.
Jim Lawson(Ball Ground GA) offered Craven from his nursery for years, but I don’t think Lawson’s is still in operation…Mr. Lawson was getting up in years when I last spoke with him, probably 10 years or more ago…
