Plant Common Name

Black Metallic Taro, Metallic Taro, Silver Leaf Elephant Ear

General Description

Black metallic taro is a tropical perennial native to Indonesia. The large leaves have a lustrous sheen that, to the eye, changes in color from dark green or black to a deep purple. The undersides are silver-purple with darker veins and the leaves' edges are wavy.

Black metallic taro prefers moderate shade and protection from scorching sun rays. It requires moist organic-rich soil, with enough drainage to allow fresh water to pass through. High humidity keeps the leaves from browning or scalding in direct sun or from breezes. It would make a large specimen houseplant for a large, bright room, a humid greenhouse or a focal point under the canopy of a large tropical shade tree.
