Where can I purchase vines
Thank you for the question. Your growing zone 3a limits your choices as does whether you want to make wine or eat the grapes. A good eating grape for your zone is Bluebell, and good-fair wine grapes are Frontenac, La Crescent, and Marquette. The wine grape varieties might not make it. Please read our publication on growing grapes for home use:
The Minnesota Grape Growers Association in an excellent resource: http://www.mngrapes.org/ I've pasted the link to their grape vine resource chart here:
Thank you for contacting Extension.
