Care? Not much really Ted. Most of these are perennials, so if you get them in the right place, they just come back year after year, and you can enjoy them, plus maybe throw a bit of fertilizer around and make sure there's water when it's dry.
The caladiums are all in pots and I move them around the yard to display them when they are looking good. Then winter them over in a protected place that's on the dry side.
The orchids are the only thing in my jungle that get constant care.
