Caladium, angel wing, is a summer bulb which, with its spectacular, colorful foliage, radiates the tropical look. This South American native is well known for its performance in shade, but new hybrids are available that are tolerant of full summer sun. The colors of the heart-shaped leaves range from bright red, pink, green and white in multiple variegation. They prefer a moist but well-drained site and grow up to 1-1/2 feet tall. Use in containers with mixed plantings or in mass for a very dramatic show. Hardy to USDA Zone 10.
