I picked-up a gunnera rhizome(?) at a sale for 99 cents in late June. I
planted it in 3 gallon pot. It tool a LONG time to sent up any growth. The
plant produced the leaves, the largest was about 4 inches across. Since I
am in zone 6, I know that it can't survive outside. My only windows for this
plant are north or east facing. Can I keep this in the pot and let it go
dormant in my basement or should I remove the rhizome from the pot and store
it like I do my cannas and dahlias?
