I am currently zone 7-ish. We reached -1 F this year, but the previous five winters saw lows only to 7F with most not below 10F. I can second nearly exactly what Lee mentions. In pots they seemed better off and I could get them going, but planted out they dwindled quickly. Most growth happened spring and fall with death always summertime. I did flower one from Ellen (Seneca Hill Perennials) and also a seed grown dracomontanum, but they died immediately after.

And in every case so far, sooner or later, they eventually dwindle to nothing, and it always happens in the summertime. I've managed to have some grow to almost fill a 15 cm/6 in. pot, and just when they get big enough that I think they will finally bloom, they start to dwindle and 1 to 3 years later I get only one leaf, then nothing. of those Zone 9 plants that also happen to want it to never get hot either. As I've mentioned before, I don't think Ina realizes just how cool the summers are in Auckland despite it never getting much below freezing in the winter, if ever.
