I have a tuber, which had many baby tubers. It bloomed once last year- magical it was. Then it dies back, grows again for a few months and dies back into a tuber. I don't understand it. Maybe it will bloom in the winter again! (in Karachi)
I have changed my view regarding this beauty. It is a plant that requires little lookafter. Tips Select a permanant place, high tree shade or shifting shade or shade it by a net as it starts sprouting Plant the tuber 4 inches deep to avoid demage by hoeing (godi), Better cordon the area. They climb by the hooks on the leaf tips and require 6-8 feet tall support. Moderate watering Leave it for years to come.
