Botanical Name

COLOCASIA affinis

Plant Common Name

Elephant Ear, Taro

General Description

A tender herbaceous perennial native to the eastern Himalayas, Colocasia affinis is grown primarily for its showy foliage. The velvety heart-shaped leaves are purple with green veins. Fragrant flowers with narrow yellow spathes may appear in summer.

Beautiful near a water feature, this plant grows well in shallow water or in any evenly moist, humus-rich, neutral to slightly acid soil (keep it drier during its winter quiescent period). In areas where the tubers will not overwinter in the ground, they can be lifted and stored in the fall, or grown in containers.
