Description
Native tufted perennial, reaching 1-4 dm in height.
Leaves are grass-like, reddish to green, with long, fine hairs along leaf margin.
Inflorescence consists of 1 to 6 brownish glomerules (a condensed, headlike, cluster of flowers). The individual flowers consist of 6 membranous pallid, brownish tepals. Luzula comosa var. laxa generally has a more open, subumbellate inflorescence than Luzula comosa var. comosa, which has a tighter capitate inflorescence.
Juncaceae family members are differentiated from grasses in that they typically feature round stems, without nodes. [2][3]
Bloom Period
April to July[2]
Distribution
BC to California, along both sides of Cascades, east to Alberta, Montana, Utah, and New Mexico.[3]
Habitat
Openings, rocky slopes, forest, and shores, coastal to montane.[3]
