The cobra lily is able to survive fire by regenerating from its roots, but despite this important role the roots are very delicate organs. Many carnivorous plant enthusiasts have succeeded in cultivating these plants, and have developed or discovered three color morphs: all green, all red, and red-green bicolor. By extension, the vegetative community found

While pollination has not yet been observed in action, it is generally expected that the pollinator is either a fly attracted to the flower's unpleasant smell or some nocturnal insect, as no extensive study has been performed to observe potential nighttime pollinators.
