I've planted it in my garden this summer and it is still in flower (December). Probably because we did not have severe frosts yet. The plant is (still?) leggy, the stems flop. Flowers last extremely long in a vase and are wonderful strong honey scented.

Update April 2014: I've just removed it carefully into the trash bin. First I thought it didn't return this spring. But when I took a better look I noticed young plants (on runners) already 1 meter from the mother plant. The fleshy roots (runners) break easy. Although I like the plant, I don't want them growing all over my garden. Hope this is it and removed all of it. I'll take a close watch on the spot for a while.

In my opinion it might be invasive!
