Colorful caladiums provide a striking contrast with the green foliage of other plants, especially when caladiums are planted in the foreground. Count on caladiums to provide summer color in shaded areas where sun-loving flowers won't grow. Varieties exhibit combinations of shades of red, pink, or white, with prominently colored midribs and contrasting backgrounds and borders. The variation in leaf color and pattern provides many uses for caladiums in the landscape. Nurseries and garden centers offer caladiums as potted plants or dormant tubers.
Tubers are available in four different sizes based on diameter and are priced accordingly.
Large tubers have more leaf buds than small tubers and, therefore, make larger and better displays. Caladiums require a warm, moist soil to grow. Planting in cool soil results in slow growth or tuber rot. A good rule of thumb in determining when to set out caladiums is to plant them when you plant okra seed in the vegetable garden. Each caladium tuber has a large central bud surrounded by several small buds.
