Darlingtonia californica
California pitcher plant
Northern California and southwestern Oregon
Overview
Darlingtonia californica is a carnivorous perennial in the pitcher-plant family, the only species in its genus. It forms clumps of hollow, tubular leaves 10–36 inches (25–90 cm) tall that twist as they rise and swell into an inflated, hooded dome at the top, finished with a forked, mustache-like appendage. The hood is dotted with translucent patches that admit light and disorient trapped insects. Prey enter through an opening beneath the hood, are drawn downward by downward-pointing hairs, and are broken down with the help of bacteria rather than the plant's own enzymes. In spring a leafless stalk rises above the pitchers bearing a single nodding flower with yellow-green sepals and dark red petals. It grows in cold, nutrient-poor seeps, bogs, and serpentine fens of northern California and Oregon, where its roots are bathed in cool flowing water. It depends on constant moisture, cool root temperatures, and mineral-poor water, and declines quickly in warm, still, or nutrient-rich conditions.
Native Range
Darlingtonia californica is native to northern California and southwestern Oregon, where it grows in scattered bogs, seeps, and serpentine fens fed by cold mountain water.Suggested Uses
It is grown in bog gardens, carnivorous-plant collections, and cool, wet container setups with mineral-free water. It is suited to specialist growers able to supply cold, pure water and cool roots.How to Identify

Bloom Information
A single nodding flower opens on a tall leafless stalk in spring, generally April to June, with yellow-green sepals and maroon petals. The flower stalk often stands taller than the pitchers. Seed capsules follow in summer.

Care & Maintenance
Care Guide
Darlingtonia californica requires cold, mineral-poor water and cool root conditions, which makes it demanding to grow. It is potted in a nutrient-free mix and watered only with rain or distilled water, never tap or mineral water. The roots must stay cool, so growers flush the pots with cold water in hot weather and place them in bright light with good airflow. It receives no fertilizer, since it draws nutrients from trapped insects. Warm stagnant water, mineral buildup, or rich soil cause rapid decline.Pruning
Dead or browned pitchers are trimmed at the base once they wither to keep the clump open. The flower stalk is removed after seed is collected or once it browns. No other pruning is needed.Container Growing
