It should be easier to find them in Canada. Honey berry USA buys all their plants from Canada. They can stand some shade, but the production will be less.I really need to find room for these. These need two different types for pollination, yes? So I’d need room for two?
Solo is very difficult to get though. I think strawberry sensation and gaint heart would be a great pair if you want late varieties. Early ones can be Aurora and Tundra or honey bee for better pollination.
