With their bulbous green heads, twisted red tongues, and long, tubular pitchers, the cobra plant is very suitably named. Darlingtonia is very closely related to the Sarracenia. There are striking similarities between it and S. minor and S. psittacina.
Cobra plants have a bad reputation for being difficult to grow.
This is not far from the truth, but the difficulty can be overcome. We recommend reading The Savage Garden to fully explore these incredible plants. Cobra plants thrive in a mix if one part long fiber sphagnum moss to one part perlite. Another good mix is two parts perlite, lava rock, and or pumice to one part peat. The mix should be airy - the rock ingredients will help cool the roots.
