Lomatium nudicaule (Barestem biscuitroot)

Large, somewhat drought tolerant native perennial with leafless stalks topped with inconspicuous yellow flowers, blooming early April to August. Found on rocky and sandy soils in foothills, shrublands and woodland openings up to 8,500 ft. elevation. Crucial early spring forage and pollen for ungulates and pollinators. Foliage and associated insects are vital early spring food for sage-grouse hens and chicks. Biscuitroots are host plants for the Anise swallowtail butterfly and the rare Indra swallowtail butterfly.
