Jim Waddick asked: " Just how hardy is G. tristes? HAs anyone in a cold
winter climate tried it outdoors?"

I grow it in my protected cold frame; when I have enough to spare, I'll try
some in sheltered spots in the garden. I've heard or read (but don't
remember where) that it's been grown in zone 7 gardens. 

For me it has definitely been a winter grower, and so I frankly doubt its
long term success in the open garden. But evidently different forms exist -
Mary Sue mentioned a late flowering form once, and that might be one to try
in marginal gardens.
