Black Stem Elephant Ear: Dramatic Foliage for Tropical Effect

Black Stem Elephant Ear (Colocasia fontanesii, syn. C. esculenta, C. violacea), also called Violet Stemmed Taro, is a striking cultivar grown for its dramatic foliage: huge, heart-shaped, matte green leaves held on tall, glossy, violet-black to purple stems. The contrast is electrifying. It forms a large, architectural clump 4-6 feet tall, adding instant tropical drama to borders and water margins.

Culture

Plant in spring after frost in rich, moisture-retentive soil, full sun to part shade. It loves heat, humidity, and ample water. In cold climates, lift corms before frost and store dry, or grow in large containers. It can be grown as a marginal aquatic plant. The stems are the star; remove older leaves to highlight them.
