Zantdeschia hardiness

Trying to grow Zantedeschia aethiopica by "glad culture" can be done, but
the results are not very good. My Z. aethiopica plants do better grown in
the greenhouse over winter and outdoors in the lath house under misting in
summer. They flourish in the greenhouse in winter, then the foliage takes
a beating when they go outdoors into the wind and weather in late
spring. They gradually recover during the summer, and may even bloom in
summer. Hybrids and selected forms of aethiopica are all slightly
different in their response to culture, in my experience.
