Evan and I have had a discussion over on the Tropicals forum about putting Caladiums in sun vs. shade in general. I've definitely had a few that did not like being in direct sunlight - burnt leaves in spots, wilting easily, generally unhappy. Others seem to make greener leaves in shade, and put on more color, red, white, yellow etc. in more sun. The Thai's don't seem to like any sun at all.
Is there any sort of rule of thumb as to which ones will tolerate sun and which ones won't? It seems counter-intuitive to me that the mostly-white ones like White Christmas and Candidum seem to tolerate quite a bit of sun, and we're talking Florida sun here! I thought for sure the white portions of the leaves would burn, like some other variegated plants do.
Thanks for any words of wisdom here. These two pics are both Carolyn Wharton, one in the deep shade of a mango tree, the other in afternoon sun.
