This is a very easy plant to grow. Use a rich soil, and keep it moist, In south Texas it does better in morning sun or dappled sunlight.

This plant is a wonderful specimen plant for the garden. In zone 8b it is not a full sun plant as advertised. Mine was in full sun and I was forced to move it to a situation where it gets morning sun and plenty of afternoon shade. Under these conditions it is thriving.

Colocasia 'Coffee Cups' was discovered in the wild by Indonesian botanist Gregory Hambali and brought to the US by aroid expert Alan Galloway. Colocasia 'Coffee Cups' makes a stunning 6' tall clump of Colocasia 'Fontanesii'-like leaves (glossy olive green) with a dark, purple-black stem. The unique feature is the dramatic leaf cupping, even more dramatic than with C. 'Big Dipper'. As the leaf fills with water, the stem gives enough for the leaf to dump out its catch before refilling...fascinating. Obviously, it performs best in freshly ground soil. C. 'Coffee Cups' sends out above-ground runners, but only in fall. All of the plants previously sold in the US under this name are actually C. 'Big Dipper'.
