Elephant's ears are lush, tropical accents that look good in any climate. These elephant's ears are hardier than their close relatives (alocasias) and their leaves are heart-shape and larger. When summer's warm weather arrives, they grow fast, achieving a large spread of at least 5 feet. Colocasias languish in drought but thrive in wet soils.
