Gardeners' Notes:

I'm able to grow them here in zone 6 Sterling, MA. Of course, I grow them in a microclimate. I have a garden bed along the south facing foundation of my house and they die back in November and sprout up again every March. No special winter care is needed as my microclimate is at least that of zone 8.

I give these a positive rating as they are beautiful plants, my only issue with them is that they are very top heavy and require stakes and string to keep them upright.
