Conservation status: CNPS 1B.3

Cook's triteleia is a rare (CNPS 1B.3) California native perennial found in the southern Santa Lucia Range in western central Coastal California, occurring in wet serpentine ravines and streamsides near cypresses at elevations below 700 meters. Flowering from May to June, this plant produces white to pale straw-colored flowers with reflexed perianth lobes, creating delicate clusters on slender stems. Growing with a scape 20 to 25 centimeters tall that is slightly rough-textured, it emerges from a grass-like base. Its leaves are narrow and elongated, reaching 10 to 20 centimeters in length, providing a slender green backdrop to the elegant floral display. The flowers feature white anthers and delicate perianth tubes 6 to 10 millimeters long, with lobes that elegantly curl back from the central stem.
