We have the Glencora seedless grapes, but I was really worried about them after the last brutal winter. Honestly, it’s still not really warm here–today was around 50 degrees. Glencoras do grow in zone 5, and they usually winter over just fine.
These vines produce medium sized juicy blue/black grapes, and once the foliage turns green, they are an excellent garden feature. Glencora grape vines are self pollinating, so no worries there, either!
Don’t be afraid to branch out to grapes–these are hardy, easy to grow, and require little care. In August, you’ll have a wonderful harvest!
