Prime-Jan Blackberry in my location?
I would like to try a blackberry in my rather harsh environment (CO mountains, zone 5a usually, and quite windy) and was thinking of trying some Prime-Jan plants next spring. They are supposed to be a primocane variety and will fruit on new canes (which is about the only way I usually get berries) and I thought they might work here. But I'd rather not waste time, money and effort on something that will never produce for me.
What do folks think? Any chance of blackberries here from this variety? (I am having some success with the spring bearing primocane raspberries FWIW).
