Colocasia esculenta ‘Royal Hawaiian Aloha’
 
Common Names Aloha Elephant Ear, Royal Hawaiian Taro, Lime-Veined Taro
 
Zones 8–11 (outdoors); Zone 7B+ with protection
 
Colocasia ‘Aloha’ is a standout in the Royal Hawaiian® series, bred for compact form, glossy foliage, and vivid lime-green veining. Its deep olive leaves shimmer with a satin finish, while the chartreuse midribs offer bold contrast. Unlike sprawling taros, ‘Aloha’ maintains a tidy clump and upright posture, ideal for containers and tropical borders.
