Description
Darlingtonia californica, often called the Cobra Lily, is a carnivorous plant native to Northern California and Western Oregon. It grows in cold, fast-moving water environments such as mountain seeps, bogs, and stream edges. These habitats stay cool year-round, even in summer. The plant relies on this constant flow of oxygen-rich water to survive. You will often find it at low to mid elevations where the soil is poor in nutrients.
The most recognisable feature of Darlingtonia californica is its tubular leaves, shaped like a rearing cobra. Each leaf forms a hollow pitcher that can reach up to 60 cm tall. At the top, a forked appendage hangs forward, resembling a snake’s tongue. The hooded structure curves over the opening and has translucent patches. These allow light in, which confuses insects and makes escape difficult.
Inside the pitcher, the surface is smooth and slightly waxy. Downward-pointing hairs guide insects deeper into the tube. Unlike many other carnivorous plants, Darlingtonia californica does not produce its own digestive enzymes. Instead, it relies on bacteria and other microorganisms to break down trapped prey. This process releases nutrients that the plant absorbs.
The plant also produces flowers in spring. These grow on tall stems and hang downward. The petals are usually yellow to reddish in colour. The shape is complex, with layered sepals and a central ovary. This structure helps protect pollen from rain and limits access to certain pollinators.
