Elephant Ears

Elephant Ears

Elephant Ears (which include Colocasias and Alocasias) provide a tropical atmosphere with their  enormous, novel, green rippled leaves and large tubers.  Also known as Taro, they are spectacular as a tall screen or as a submerged pot plant for water gardens.  With leaves up to 2’ long, they thrive in partial to full shade and moist soil conditions.  Zones 7-11.   Elsewhere, dig and store or use as a houseplant for an exotic look.

If you have a large pot, Elephant Ears can provide tropical interest in a Northern garden.
