I bought the tubers from Caladium World

Here's a good article on care

I haven't had success with them going dormant & re-growing in the
same pot....they decayed even though I let them go dry.
I also tried lifting them earlier when they still had top growth but it was obviously
dying back, and did get some tubers, but they weren't robust as when I planted them.
But I will buy them every year if I have to.....they are just so pretty inside
in the livingroom, or outside by the couch.
