Caladium bicolor (Heart of Jesus)
Native from Central America to northwestern Argentina, this tuberous perennial herb forms clumps about 1 to 3 feet tall. Its thin, heart-shaped or arrowhead-shaped leaves come in many cultivated patterns of green, white, pink, and red. Small flowers are clustered on a spadix surrounded by a pale green spathe. The foliage can die back when conditions become unsuitable, while the underground tubers remain dormant until growth resumes. Plants are propagated by dividing the tubers. All parts contain needle-shaped calcium oxalate crystals that can irritate the skin, mouth, and throat and are harmful if eaten. Photographed in Colombia and Florida.
