Darlingtonia is a monotypic genus native to the west coast of Oregon and north-west coast of California. The genus Darlingtonia was named by John Torrey in 1853 to honor his friend, Dr. William Darlington. The leaves of Darlingtonia resemble a cobra ready to attack, which gave Darlingtonia the common name of cobra lily.

This plant is not a beginners' plant, since it likes sunny summers but cool waters/roots. You can overcome this issue by having a water chiller or by adding cold water to its tray.

 

Plants are shipped potted in a 2.5 x 3.5" pot.

Small plants are about 1-1.5" tall

Medium plants are about 2-3" tall

Large plants are about 4-5" tall
