These caladiums, as with others, can be used as single specimen accents or planted in groups for a dramatic-looking tropical display. The 12-30 inch heart shaped leaves will retain their color throughout the summer and into the early fall if treated properly. But before you decide to grow fancy leaf caladiums, there are a few things you should know about them and their care. Fancy leaf caladiums or Caladium x hortulanum originated in Peru and around the Amazon Basin in Brazil. Outside of the tropic zones they are usually grown as warm weather annuals. In northern climes, they’re used both as bedding and potted plants for display in the garden or on the porch. In the spring, you can buy these gorgeous plants full grown from the nursery or florist, but it’s much more economical and, in this gardener’s opinion, much more fun to grow fancy leaf caladium bulbs on your own.
