Colocasias can be grown from eddo tubers that can be bought from fruit and veg shops. Eddoes are a common food crop in Asia, being treated similar to a sweet potato.
To get the plant going wrap in a moist plastic bag and leave on a heat mat and when it shows signs of growth pot on to a proper plant pot and plant with the pointed end a couple of centimeters deep.

They must be kept warm and above 20c.

Colocasia leaves can reach enormous size and fully live up to their more common name of elephant ears!
