Trifolium longipes subsp. atrorubens

Family: Fabaceae · Type: perennial · Native

Dark-colored trifolium is a California native perennial found in northern Coast Ranges, Sierra Nevada, San Bernardino Mountains, and San Jacinto Mountains in dry or boggy meadows, open slopes, woodland, and subalpine areas at elevations of 1,100 to 3,000 meters. Flowering from June to September, this plant produces white to purple flowers with densely long-hairy calyx lobes. Growing with thickened, fusiform roots and short stems, it forms low-spreading clumps in mountain habitats. Its leaves have short-elliptic leaflets approximately 2.5 to 6 times longer than wide, with obtuse tips. The flowers spread or rise slightly above the foliage, creating delicate clusters in alpine and woodland environments.
