My information says that it is hardy in zones 3-9 and can tolerate partial sun. I have found that it is very hardy and, for me anyway, drought tolerant. Last year we had severe drought and I never watered it. I tried moving it and left some of the root by accident. Despite this abuse and neglect, it still came back.

This plant gets very high, so only from a distance you can see that it is flowering. The leaves more down are huge also..I've measured them 100 cm easy..sometimes I rip one leaf off to use it as a shelter in a suddenly rainfall.. It can take more drought than expected...
