successive ripening blackberry varieties?
After reading reports on blackberry varieties on this forum, I'm interested in the following blackberry / hybrid varieties based on reports of flavor. (I live in zone 5, but they will be grown in pots and overwintered inside.) I'm just a backyard gardener growing for fresh eating, so I'm looking for successive ripening. After researching, I'm guessing that the varieties I'm considering ripen in the following order:
Siskiyou, Boysenberry (pretty much at the same time?)
Newberry (aka ruby boysenberry), black diamond, osage (pretty much same time?)
Can anyone correct or confirm any portion of the ripening order listed above?
I prefer fruit that is delicious fresh with only a little sugar at most. Am I missing a potential variety that is sweet enough on it's own? Any other suggestions regarding the varieties on the list?
Any ideas where to get wyeberry? After speaking with them several times, it sounds like edible landscaping has dropped them.
