These are some rhizomes from last year. I tried to grow them in the yard with little success. They didn't fair so well during the summer here in southern KY. I thought this area would be ideal but they seemed to just get too hot...maybe...during the fall they started to rebound and looked pretty nice at about 12 inches high. Then they started to suffer the winter brute. So, long story short, I moved them into the house in large 5 gallon pots. I have some bay windows that face the south in the breakfast area and they are sprouting up again and looking great. Any thing else that I should be concerned with?
