Yes. A nursery in TN has them. My g’mother used to make Huckleberry pie. LOVE IT!I only know about wild huckleberries, no experience with cultivated varieties. Wild huckleberries are a large part of outdooring around these parts though. Are you thinking of growing some or just curios?
Grew those as a kid-one time..... they were terrible when ripe. Left them till after frost, still terrible. Think they are black nightshade......should be a law against them. Unless someone knows how to fix them. They were tall and loaded.Apparently "huckleberry" can refer to more than one plant. The one I am familiar with is the Garden Huckleberry, Solanum melanocerasum, a member of the nightshade family.
I've never grown them personally; but I visited SSE's farm in Iowa over the Labor Day weekend, and they had some growing in one of their fields. They were impressive, I wish I had taken a photo. Stout bushes about 2-3' tall, heavily loaded with 1/2" - 3/4" glossy black berries, in large clusters. The plants had dropped their leaves (making all of the berries visible), and all the berries appeared to be ripe... so if that is the huckleberry you are looking for, @seedcorn , you should have no trouble growing them in your climate. SSE sells seed for both Garden Huckleberry, and the closely related Sunberry (a.k.a Wonderberry, supposedly developed by Luther Burbank). I assume they would be started as transplants, same as tomatoes.
