Caladium

The genus Caladium includes seven species that are native to South America and Central America, and naturalized in India, parts of Africa, and various tropical islands.  They grow in open areas of the forest and on the banks of rivers and go dormant during the dry season. The wild plants grow to 15–35 inches (40–90 cm) tall, with leaves mostly 6-18 inches (15–45 cm) long and broad. Caladiums grow from tubers and can be propagated by dividing the tubers. They are hardy only to USDA plant hardiness zone 10; in colder areas, they are typically grown as tender “bulb”s or as houseplants.
