Colocasia esculenta ‘Blue Hawaii’ (Taro)

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.
