Colocasia esculenta ‘Black Coral’ (Taro) is a tuberous, frost-tender perennial with long-stalked, glossy, heart-shaped, jet-black leaves. Unlike the leaves of Alocasia which point skyward, the leaves of Colocasia droop and point toward the ground. Reminiscent of calla lily flowers, the blossoms consist of a yellowish-green spathe and spadix. They are not particularly showy and are infrequently produced. ‘Black Coral’ is a hassle-free tropical that makes an unforgettable focal point and creates a compelling backdrop for most brighter plants. Outstanding as a container plant.
- Grows up to 4 ft. tall (120 cm) and 3 ft. wide (90 cm)
- Performs best in sun or part shade in organically rich, moist to wet soils. Provide a sheltered location to protect the decorative leaves from strong winds. Best leaf color production in sun.
- Elephant Ears love water and nutrients. They require regular watering, particularly during dry summer periods. Provide regular fertilization during the growing season. The more you feed them, the larger they will grow. They can be planted in up to 6 in. (15 cm) standing water.
- Perfect as a specimen or in groups for beds and borders, near streams and ponds or in large containers.
- Generally disease free. Watch for glasshouse red spider mite, aphids and glasshouse whitefly.
- All parts may cause mild stomach upset if ingesting without cooking.
- Native to tropical eastern Asia, Colocasia esculenta species was first brought to the Americas as a food crop for slaves. It was later promoted as an alternative crop to potatoes. Colocasia esculenta can tolerate a wide range of wet to dry sites and can easily invade wetland edges, swamps, blackwater streams and riverine forests.
