Does this plant die back in winter and lose it's leaves?
I have tried growing this plant a couple of times. The first time I grew this plant I was thrilled with it, but failed to overwinter it. I'm trying again this year.
It can be grown in the garden, or as a house plant.
If grown in the garden then I understand that it should be treated in a roughly simiar manner to dahlias. It has a similar sort of tuber which should be lifted and stored in a 'frost free' place over Winter.
It can also be grown as a houseplant. I'm not exactly sure what happens then. I aniticipate that most of the foliage will die down during the Winter.
When I tried, I tried to overwinter in a frost-free greenhouse. The tubers did not come to life in the Spring. My guess is that the greenhouse, although frost free, was far too cool. A website about growing this as a houseplant says that the minimum overwintering temperature is 60F or 16C. My frost-free greenhouse was a lot colder than that.
This year I intend to bring the tubers inside the house.
Some instructions for growing as a house plant are here:
