They're called Cascade berries. I suppose they're similar to Marion berries etc. I read they are a cross between a Logan berry and our little native blackberries. They have long vines, thorns and a very strong will to live and propagate themselves! They are worth it, at least for now.
Interesting! Are they seedy, then, like a blackberry? I've been trying to get Montana to send me slips of huckleberries since I was there in 1975 or so, but last time I contacted them they claimed they are still "researching" the things. I'd be happy to "research" them here. They're like a ginormous blueberry with a little ring or ridge around the bottom, so they sit up on their little bottoms. I'm not going to tell you where they grow, but I could just about sit on MY bottom and fill up a one-gallon ice cream bucket without moving, hardly, if I didn't eat any. Time and distance may be causing me to exaggerate a bit, but not much. . .
ETa: no thorns, either.
