The caladium will be fine with the elephant ears; they like similar
conditions. 42 degrees is a bit too chilly, though. I don't put mine
outside at anything under 55, and they really need heat, 70's and 80's to
grow well.

Anyone here growing elephant Ears? I put an enormous tuber in a big pot
and
I'm thinking of adding a ring of Caladiums too. Does anyone know if they
will work well together and if these Ears will be ok outside in 42 degree
weather?
