Clustered lady's-slipper

Family: Orchidaceae · Type: perennial · Native

Conservation status: CNPS 4.2

Clustered lady's-slipper is a California native perennial with a rare (CNPS 4.2) status found in northwestern California, northern Sierra Nevada, and southwestern San Francisco Bay bioregions in mesic to moist, shady conifer forest at elevations of 100 to 2,000 meters. Flowering from March to July, this plant produces yellow-green and purple flowers with distinctive nodding blooms and a characteristically shaped slipper-like lip. Growing 12 to 20 centimeters tall with a delicate, clustered appearance, it emerges with two opposite, wide-elliptic leaves each 5 to 12 centimeters long. Its leaves are a rich green with an elegant, broad shape, and the flowers feature a complex coloration with upper sepals in green to brown tones and lateral petals that curve downward. The plant bears between 1 to 14 flowers in a loose cluster, creating a subtle yet intricate botanical display in its forest understory habitat.
