Black Sapphire Elephant Ear

Black Sapphire Elephant Ear (Colocasia 'Black Sapphire')

Black Sapphire Elephant Ear is a dramatic tropical foliage plant valued for its satin-black leaves, dark stems, and bold warm-season presence. Its large, glossy foliage shifts with the light, creating a deep black to purple-black effect that brings strong contrast to patios, poolside plantings, large containers, moist garden beds, and tropical-style landscapes. This clumping elephant ear delivers the lush scale of Colocasia with a polished dark-leaved look that stands out without relying on flowers. With warmth, rich soil, steady moisture, and sun to partial shade, Black Sapphire Elephant Ear adds depth, texture, and tropical character to indoor and outdoor displays.

Distinctive Features

Black Sapphire Elephant Ear produces large dark leaves with a satin sheen, giving the foliage a rich black to deep purple appearance depending on light and maturity. The undersides of the leaves can show maroon coloring, while dark stems strengthen the plant's overall dramatic look. It forms a tight clump rather than a loose running habit, making it easier to use in containers and designed beds. Flowers may appear occasionally as a spathe and spadix, but this plant is grown primarily for its bold foliage, dark color, and tropical form.

Growing Conditions

• Sun: Grows best in full sun to partial shade, with brighter light often supporting deeper 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 regular moisture during active growth and can also be used in shallow bog or pond-edge conditions where drainage and water quality are appropriate.
• USDA Zones: Hardy outdoors in USDA Zones 7 to 10 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 3 to 4 feet wide in favorable outdoor conditions, while container-grown plants may stay smaller.
• Habit: Forms an upright, clumping tropical plant with large dark leaves rising from the base on sturdy petioles.

Ideal Uses

• Focal Point: Use as a bold 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 and dark stems 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 love of moisture 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 foliage 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.
