Caladiums are tropical perennial bulbs that have heart shaped leaves. Over 1,000 varieties of caladiums have been cultivated from the native Caladium bicolor of South America.
Cladiums don't have stems. Leaf stems protrude directly from the underground tuber and are typically 6 to 12 inches long. The leaf stem connects to the center of the leaf, rather than at one end.
Caladium leaves are 6 to 12 inches long and have spotted or streaking colors of red, pink, gray or white. Depending on the variety, the leaves are shaped like a heart, lance or arrowhead.
Caladiums require well draining soil that is rich in humus. They prefer a slightly acidic soil pH.
Caladiums should be watered two to three times a week. Caladiums can't survive in dry climates.
Caladiums make good additions to borders and shady beds. They blend well with ferns and gingers.
Contact with caladiums may irritate the skin. Ingestion will cause swelling of the mouth and throat.
