Best raspberries for northern MN
I would like to plant raspberries this year but am not sure what performs best in zone 3a. I looked at the Canadian forum where a poster has a list of 11 types of raspberries she has tried over the years. Out of the 11 she has discarded the old northern stand-bys like Boyne (berries too small) Autumn Bliss (berries too tart & don't ripen in time), etc. She is now growing Viking raspberries and has managed to cross a Viking with an Autumn Bliss for a "great berry". Have googled "Viking" and can't find it listed anywhere. Would love to hear which raspberries others in MN are successfully growing and from anyone that might know where to find the Vikings.
