The promise of delicate summer color from the lovely, heart-shaped leaves of caladiums entices gardeners every year around this time. Late spring, when the soil has warmed sufficiently, is the best season to put caladium bulbs or plants in the ground.
The main source of survival for caladiums is moisture. Do not let these plants dry out, or they will die before you can say Caladium x hortulanum. Most will not do well in full sun either, but there are a few varieties (especially the whiter ones) that seem to have more sun tolerance.
Remember, these plants originated in the Amazon, so think “jungle”: heat, moisture and shade. They also like slightly acid soil, so amend with a good acid planting mix before planting, if necessary for your soil. Bulbs can be stored in a dry, cool location once the foliage has died back in the fall.
Mostly, caladiums will provide gorgeous tropical color as a border plant or in window boxes and containers. Nothing brightens up a dark corner like caladiums in brilliant red, flecked pink, white and green, or marbled deep rose hues. Feel free to mix and match, too!
