Primarily grown for its spectacular foliage, Colocasia esculenta ‘Blue Hawaii’ (Taro) is a tuberous, frost-tender perennial with long-stalked, heart-shaped, fresh green leaves. Held on semi-glossy, dark burgundy stems, the large, undulating leaves are adorned with bluish-purple edges and veins. 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. ‘Blue Hawaii’ is a hassle-free tropical that makes an unforgettable focal point and brings a distinctly tropical look to the garden.

  • 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.
