I grow plants supplied as G tuberosum, G charlsii, G malviflorum, G transversale and G transversale laccinatum. The last four came from Janis Ruksans a few years ago. They all went to - 18 C or so last winter with no problems, charlesii is still only one tuber - I suspect it would be better in the ground than in a pot. They all tollerate drought in summer. I also grow Pelargonium endlicherianum which self seeds in the sand on the Juno bench. It will grow into the automne if given adequate water and flowers all summer.
