Nursery contributed plant descriptions

Colocasia gigantea is an outrageous, fast growing tropical landscape plant well worth growing for the looks of fascination and delight. In a single season, a well fed and watered 4” pot will grow into a monster plant reaching 6-10’ tall with large rounded, powdery green leaves that look like giant elephant ears. Use as a fast growing annual in your summer garden for a dramatic tropical effect. In the winter, dig the tubers and place in the cellar or prune the plant and bring inside. Colocasia gigantea is also called ‘Giant Taro’ since the starchy tubers are eaten in some parts of the world.
