Hey! That is a great thread, I need a help, too. That webpage of Fibrex does not state differences between similar varieties. I am now very confused about two of them: - hedera colchica Dentata Variegata - hedera canariensis Gloire de Marengo The both look alike. However, the second one is not supposed to survive hard frost. I live in Prague, Czech Rep., which is zone 7 (6b) and I saw a beautiful plant there which looks rather like Gloire de Marengo, or is it the first one? Can anyone help identify? I guess the nurseries are rather mixed up about it, too. Thanks!
