Caladiums have almost unparalleled foliage and they can make showy houseplants.They can easily give you the visual impact of flowers while only being foliage plants.
Caladiums are a seasonal plant even in the tropics, where gardeners plant them in the spring and summer months when they'll thrive in the heat and wet. In the home situation, they'll do best with lots of heat, bright but indirect light, and plenty of humidity. Even under the best conditions, caladiums will only last a few months before their leaves start to die back and the plant goes dormant again. This is okay—they're supposed to do that. Use masses of them as striking summer accents and conversation pieces. When they die back, save the tubers in a bag and replant next year for another show.
