Black Coral Elephant Ear

Black Coral Elephant Ear (Colocasia esculenta 'Black Coral')

Black Coral Elephant Ear is a dramatic tropical foliage plant valued for its glossy black leaves, blue-toned veining, and bold warm-season presence. Its large, heart-shaped foliage brings deep color and strong contrast to patios, poolside plantings, large containers, moist garden beds, and tropical-style landscapes. This clumping elephant ear offers a polished, reflective look that stands out without relying on flowers for impact. With warmth, rich soil, steady moisture, and sun to partial shade, Black Coral Elephant Ear adds depth, texture, and tropical character to indoor and outdoor displays.

Distinctive Features

Black Coral Elephant Ear produces large, glossy leaves in deep purple-black to near-black tones, often with blue to blue-green veining that becomes more noticeable as the foliage matures. The leaves have a smooth, reflective surface that gives the plant a sleek look compared with more matte dark-leaved selections. It forms a strong upright to spreading clump that can fill out quickly during warm weather when provided with moisture, fertility, and heat. Flowers may appear occasionally as a spathe and spadix, but this plant is grown primarily for its dark foliage, tropical texture, and high-impact color.

Growing Conditions

• Sun: Grows best in full sun to partial shade, with brighter light often supporting darker foliage color when moisture is consistent.
• Soil: Prefers fertile, humusy, organically rich soil that stays consistently moist while still supporting healthy root growth.
• Water: Performs best with medium to wet soil and should not be allowed to dry out completely during active warm-season growth.
• USDA Zones: Hardy outdoors in USDA Zones 7 to 12 in protected conditions, while colder climates should treat it as a seasonal container plant or overwinter the tubers indoors.
• Mature Size: Typically reaches about 3 to 4 feet tall and 2 to 3 feet wide in favorable outdoor conditions, with larger size possible in warm, well-watered sites.
• Habit: Forms an upright to spreading clump with large dark leaves rising from the base on sturdy petioles.

Ideal Uses

• Focal Point: Use as a glossy dark-foliage focal point in large containers, patios, poolside plantings, courtyard beds, tropical-style landscapes, or moist garden areas.
• Container Planting: Grow in a large decorative pot where its black foliage can provide strong contrast and be moved or protected before cold weather.
• Moist Garden: Plant in consistently moist beds, rain gardens, or pond-edge settings where its tolerance for wet soil can support strong growth.
• Tropical Garden: Pair with cannas, bananas, caladiums, gingers, coleus, and chartreuse foliage plants to create a lush warm-season display.
• Mixed Border: Use in large mixed beds where its dark glossy leaves can add depth, contrast, and bold texture behind lower plants.

Low Maintenance Care

• Watering: Water regularly during active growth to keep the soil consistently moist, especially in containers and hot summer weather.
• Mulching: Apply mulch around outdoor plants to conserve moisture, moderate soil temperature, and reduce weed competition.
• Fertilizing: Feed during the active growing season with a balanced fertilizer to support large foliage and vigorous growth.
• Wind Protection: Site in a sheltered location because strong wind can tear or damage the large ornamental leaves.
• Overwintering: Lift and store tubers or move containers indoors before frost in climates where the plant is not reliably hardy.
• Leaf Cleanup: Remove yellowing, torn, or frost-damaged leaves as needed to keep the plant looking clean and encourage fresh growth.
