They’re also known as Elephant Ears and it’s easy to see why. The big, dramatic leaves certainly bear a resemblance to those of our iconic pachyderm, and the plant’s southeast Asian origins are as tropical as you could wish. When grown as pot plants in warm conditions, many Colocasias are happy to remain evergreen. Otherwise, expect winter dormancy with the plants’ growth becoming stronger every year as the corm develops. The bloom is a simple spathe which, though pretty, is outperformed by the showy foliage. When it comes to creating a tropical atmosphere, Elephant Ears are absolute must-haves!
