There are numerous varieties on the market. Caladiums have a vast range of leaf forms and color combinations including red, pink, white, green, and yellow. These blooms should generally be removed from the plant before they go to seed in order to conserve energy for the tuber. The major enemies of caladiums are too much sun, cold weather, strong winds, beating rain, or too much water. Insect and disease pests are minor.
Caladiums grow best in partial or full shade.
During the growing season, caladiums need warmth and moisture. They should have a minimum indoor temperature of 75 o in summer and 55 o in winter. The tubers should be started in February. When roots are from 1 -3 inches long, pot the tubers separately in 4 inch pots. After potting, they must be kept warm and in a fairly moist atmosphere, free from hot scorching sunshine.
