Darkness of leaves is directly proportional to how much light they get. The brighter and longer the light, the darker the leaf. Usually will fail to become very dark indoors. If in a pot, will still propagate by adventitious roots in the pot. This plant will usually crowd itself in a pot in less than one growing season.

This plant, Elephant Ear (Colocasia esculenta 'Black Runner'), and are the same plant!
They have ruffled leaves, and spread vigorously by way of runners (stolons).

It's my understanding that this is a hybrid of C. Black Magic X C. Green Ruffle

Black Runner lives up to its name when planted in the ground. It will send out runners everywhere and could become quickly invasive. I have never seen this happen when grown in pots.
