I was given two plants as a thank-you. Being an outdoor gardener, these were new ones for me. I was told that they are elephant ears. I have been trying to read up on their care. My first question is there a difference between Caladium and Colocasia? My second question: How should I care for these? I am pretty sure that in zone 5, I should take them in before a frost. The leaves will die down as I gradually cut down the water and then store them in peat moss in my basement. Any input would be greatly appreciated.
