Trifolium longipes subsp. oreganum

Family: Fabaceae · Type: perennial · Native

Oregon long-stalked clover is a California native perennial found in the Klamath Ranges and northern Coast Ranges in forested slopes, gravelly meadows, and serpentine areas at elevations of 1,200 to 1,800 meters. Flowering from June to August, this plant produces predominantly white flowers in clusters with petals that are short-tapered and quickly become reflexed. Growing with slender stems that are not densely clustered, it reaches moderate heights typical of meadow clovers. Its leaves feature distinctive leaflets that are two to five times longer than they are wide, creating a delicate, elongated appearance. The plant's calyx lobes are notably longer than the calyx tube, adding to its distinctive structural characteristics.
