From Bill at Caladiums4less. I bought two of them last year and dug them up and overwintered them and ordered 2 more this year. They are big not what they would be in a warmer zone where they have a longer growing cycle but pretty impressive to me. I planted them the last week of May and it seemed to take them awhile to get going. The colder ground temps I guess. How do you do with your Zone 5?
