Bloodleaf (Iresine herbstii) is also called chicken-gizzard, beefsteak plant, or Formosa bloodleaf. Iresine bloodleaf plants are native to Brazil where they thrive in warm temperatures and bright sunlight. In their native environment, the plants reach heights of up to 5 feet (1.5 m.) with a spread of 3 feet (91 cm.), but when grown as annuals or potted plants they only grow 12 to 18 inches (30-46 cm.) tall.
