Keep these plants well watered and fertilize them regularly for continuous bloom. These beauties work well in containers and can be brought indoors in the fall for winter enjoyment. Those tuberous begonias left outdoors should be carefully dug after a killing frost. Dry tubers in a warm, dry location for approximately 2 weeks. Afterwards store in a box or sack with sphagnum moss or vermiculite in a frost-free area until replanting in spring.
Caladium forms a true tuber or enlarged underground stem.
New tubers grow from the side of the original one. This plant is cherished for its foliage rather than its flowers. With its vivid foliage colors of red, pink, green, and white, it will brighten the darkest spots in the garden. Many varieties are available with contrasting leaf venation colors and patterns. Plants generally stay 12-18 inches tall.
