I'm looking for variety of ~preferably~ a table grape but would settle for a Concord-type, which is hardy in Zone 3a. If there is such a critter. Can anyone out there help me?
You'll want to read the following: Cold Hardy Grapes via the University of Minnesota Growing Grapes in Manitoba
Thanks, Daniel. I'd seen the U of MN brochure before & was disappointed to see that everything they're working on is still marginal in Zone 3 & sometimes 4. The Manitoba study was very helpful, however. Now the search is on to find the two varieties I'd like to try!
