Caladium Caladium bicolor , usually just called caladium, is a tropical plant primarily from Brazil grown for its strikingly colored foliage.
Caladiums have large, arrowhead-shaped leaves that are often bicolored or tricolored.
Massed together in the garden, they make an eye-catching splash of color and work well as a background for smaller blooming plants. They grow well in moderate or dappled shade and add a sparkle of color to shady sections of the garden. Definitely protect the plants from hot, mid-day sun. For the showiest display, buy the largest tubers available. Choose an area with loose soil, high in organic matter and with good soil drainage.
