Caladiums are an interesting plant, I tend to think of them as a showoff of sorts, or a Jackson Pollock canvas with paint strewn around.
They prefer warm temperatures, in fact the warmer the better, indirect sunlight, and plenty of water – but will also do well indoors if conditions are to their liking.
My experience has been that they will acclimate to a degree, endure cool nights as long as the days as warm. By cool I mean upper fifties to sixties as there is a susceptibility about them.
Caladiums aren’t edible and I know of no benefits assigned to them other than the joy of looking at and admiring them.
They’ll do well in the winter if brought indoors, but an alternative is saving the tuberous root they produce and replanting when the weather is more to their liking.
On a moonlit night white Caladiums are striking, almost ghostly, and never fail to remind me of a time when I was about eight or so, it was night time and I saw what looked like a white flag hovering above the ground waving back and forth.
I didn’t have a clue what it was and probably a little apprehensive so I called my dog and noticed he had no desire to investigate.
This was a dog who knew no fear and that raised the apprehension factor – as we inched forward I came to understand my dogs lack of willingness as it was a skunk with tail held erect and the white stripe was illuminated by the moonlight.
We were upwind but apparently my dogs vision or sense of smell was better than mine.
This was a dog who when younger had tangled with a skunk and arrived at the conclusion that when it comes to skunks discretion is the better part of valor.
The second photo obviously isn’t a Caladium, it’s a Coleus I was doing a little hdr with and it was suggested I add it.
