Borneo King Elephant Ear

Borneo King Elephant Ear (Alocasia x 'Borneo King')

Borneo King Elephant Ear is a dramatic tropical plant valued for its enormous upright foliage, fast warm-season growth, and bold architectural presence. Its large green leaves bring a lush, resort-style look to patios, poolside plantings, large containers, and protected garden beds. In cold climates, it can be grown outdoors for the summer and moved indoors or protected before frost. With warmth, rich soil, steady moisture, and shelter from strong wind, Borneo King Elephant Ear creates impressive scale and tropical texture in both seasonal and frost-free landscapes.

Distinctive Features

Borneo King Elephant Ear produces huge green leaves that are held upright on sturdy stems, giving the plant a strong vertical form. Mature leaves can become several feet long and may develop a lightly rippled or wavy surface as the plant gains size. This selection is often grown for its vigorous growth and large tropical appearance, with outdoor plants reaching impressive height during a warm growing season. Flowers may occur on mature plants as a spathe and spadix, but the main ornamental value is the oversized foliage and commanding upright habit.

Growing Conditions

• Sun: Grows best in filtered sun, bright indirect light, or partial shade, with protection from harsh afternoon sun in hot climates.
• Soil: Prefers fertile, organically rich, well-drained soil that holds consistent moisture without staying stagnant or sour.
• Water: Performs best with regular moisture during active growth and should not be allowed to dry out completely in warm weather.
• USDA Zones: Hardy outdoors in USDA Zones 8 to 11 in protected conditions, while colder climates should treat it as a seasonal patio plant, houseplant, or overwintered container plant.
• Mature Size: Typically reaches about 6 to 10 feet tall and 5 to 7 feet wide outdoors in warm climates, while indoor or container plants usually stay smaller.
• Habit: Forms a large upright tropical plant with massive leaves rising from a clumping base on tall, sturdy stems.

Ideal Uses

• Focal Point: Use as a bold tropical focal point in large containers, poolside plantings, patios, courtyard gardens, or protected landscape beds where its oversized foliage can stand out.
• Patio Container: Grow in a large decorative pot to create dramatic summer height and texture that can be moved or protected before frost.
• Tropical Garden: Plant with bananas, cannas, caladiums, gingers, and other bold foliage plants for a lush layered effect in warm-season displays.
• Indoor Feature: Use in bright interior spaces with enough room, warmth, and humidity to support its large leaves and upright growth.
• Back of Bed: Place toward the rear of large beds or borders where its height and foliage can create a dramatic backdrop for lower plants.

Low Maintenance Care

• Watering: Water regularly during active growth to keep the soil evenly moist, then reduce watering when growth slows in cooler seasons.
• Humidity: Provide higher humidity when grown indoors or in dry climates to help reduce leaf edge browning and stress.
• Wind Protection: Site in a sheltered location because strong wind can tear or damage the large ornamental leaves.
• Fertilizing: Feed during the active growing season with a balanced fertilizer to support large foliage and vigorous growth.
• Overwintering: Move container plants indoors before frost or protect dormant plants in mild climates according to local winter conditions.
• Leaf Cleanup: Remove yellowing, torn, or spent leaves as needed to keep the plant looking clean and encourage fresh growth.
