Colocasia Royal Hawaiian® Blue Hawaii Elephant Ear Bulb

Colocasia Royal Hawaiian® Blue Hawaii Elephant Ear is a tropical masterpiece that adds bold elegance to any space. Growing up to 36 inches tall—and even reaching 50 inches under optimal conditions—it showcases large, heart-shaped matte green leaves with prominent bluish-purple veins and undulating margins. The semi-glossy, burgundy-colored stems further enhance its dramatic appeal, making Blue Hawaii a true standout. Occasionally, it may produce yellowish-green spathes, though these are usually hidden by its lush foliage.

A frost-sensitive Colocasia esculenta perennial, Blue Hawaii thrives in Zones 8-12 and features a tidy, upright clumping habit. Perfect for container gardens, it can also be grown indoors in bright, sunny spaces. It excels in pond margins and rain gardens, where its bold foliage creates a tropical focal point. Whether planted solo or grouped with flowering companions, this elephant ear delivers an extraordinary visual impact.

Low maintenance yet stunning, Blue Hawaii thrives in sunny to partially shaded areas with rich, fertile soil that ranges from medium to wet. Consistently moist soil is essential for its success, and in hot summer climates, providing some afternoon shade helps maintain its vigor. Its deer-resistant nature makes it a practical choice for gardeners seeking beauty without hassle.

Plant the 9- to 11-inch rhizome in mid-spring, spacing bulbs 18 to 24 inches apart and burying them 2 to 4 inches deep. Ensure soil and air temperatures consistently exceed 60°F. In colder climates, lift the bulbs in fall and store them in a cool, dry location where temperatures remain above 45°F. Replant in spring for another season of tropical allure.
