Seeing as how it is been several years since it has been in cultivation, i was wondering if anyone has any information / experience about hardiness or cultural requirements for this plant. Is anyone keeping one alive? Are they becoming more available?
Hi, here it's zone 5. I had two in the ground and only roots survived that winter. Now I have another one in a pot and it needs shelter during winter. This winter I keep it in a greenhouse, pot in the ground. When it's not sunny (always during night) it gets almost as cold as outside and I am not sure it will survive.
