Jely, Caladiums can be grown indoors, but they honestly do best outside..
What type of light is it growing in? Also, what temp? They need bright light conditions, w/o direct south or west exposure.
Soil should be kept slightly moist, but drying a bit between waterings is fine.
Have you fertilized? If you've a bulb fertlilzer that'd be best, otherwise use a foliage type food, but I'd dilute it by half.
Since they're tropical plants, they enjoy humidity. If you use ac, it'll take moisture from the air..Misting will help, and/or placing pot atop pebble tray filled w/water..Toni

I'm having the same issue with my caladium, stems and leaves drooping. It is kept very moist and humidity levels are very high here right now. It's in a shady spot, perhaps it needs a little better light?

Debbie, yep, give a bit more light..bright light is fine..as long as you keep an eye on soil they should do well..the more sun, the more pronounced coloring will be. But no direct sun, just bright light..Toni
