I am trying to locate someone who has a soveriegn rose grape vine, which I believe is a cross of bath x perle of csaba. This vine was developed in BC at the Summerland research station in the 1970's and i'd like to get some cuttings and try to grow a few of these vines. They appear very interesting on paper.. I've contacted the Summerland station and they no of know one who may still have it.
This variety is held at the Center for Plant Health in Sidney. They may be able to provide you with the name(s) of previous purchasers. My name is on the list but we had zero survival of that particular planting so I can't offer you any cuttings. Ralph Walton, Greenridge Farm, Denman Island. (temporarily closed)
