Hi all. I'm in the Great Falls MT area and experimenting with cold Hardy grapes. Currently have a couple vines each of valiant, frontenac Gris and la crescent (2 yrs old) and some one yr old Brianna, Osceola Muscat, Frontenac Blanc and somerset seedless vines. Also have some rooted edelweiss cuttings that were given to me that I will try this year as well I want all the varieties to find out which grow best yr after year in our harsh climate then begin replacing and Inceasing vines from there. Would love to hear anyone else's input on prairie Hardy vines in areas with variable winter temps but potential for extreme cold as well as short growing season and fairly strong winds during the winter months.
