Unless you live in a hot dry climate, (the best for grapes) then you need a variety that can handle rain and humidity. Also even grapes that are grafted selected varieties for your area, purchased from a nursery take 3 years to fruit. So from a seed, maybe 5 at least. Never heard of anyone planting them from seed. Most fruit planted from seed isnt "true to seed" so you never know after waiting years for your plant to fruit, if it will be anything like the grapes it came from. Or if it will be any good. Buy a cheap grape vine from a nursery this winter or spring if your somewhere cold. THeyre like 5 bucks.
