I dont ever think of Caladiums as anything more than an annual.
They are show stoppers and just a couple of bulbs in a container go further than 2 annual plants for so much more. Annuals here are going for 5 dollars each,thats 5 caladium bulbs.
I admit I lavish myself where the summer garden is concerned. I live on a fixed income at 78 and withy my DD and SIL so the income goes further than it did when I had taxes and other home owner expenses.
It's a luxury to be in this position after 50 years of child support and art business and teaching.
Enough of that. Caladiums are tropicals and like it hot.I stated awhile ago,I plant bulbs the end of May when all the other containers are planted. They grow fast when the real hot weather comes and nights are in the 60"s.
This is Moonlight ad Lynn said a white caladium in shade is really beautiful.
