Place your plant in a location with plenty of sunshine, warmth and that is relatively humid. Plant your cobra lily in moss to replicate its natural environment.
Water your cobra lily daily. The roots of the cobra lily need to be kept cooler than the rest of the plant. Cool the roots by placing ice cubes on top of the soil, but away from the plant's leaves.
Drop flies or other insects into your plant about every six weeks. Carnivorous plants devour insects to supplement their diets, since the soil in their natural environment is low in nutrients.
