Lomatium dissectum (Fernleaf biscuitroot)

Very large, drought tolerant native perennial with inconspicuous yellow to brownish-purple flowers, blooming late March to August. Largest of the biscuitroots. Common on rocky semi-desert foothills, shrub-steppe and woodland openings; up to 11,000 ft. elevation. Early spring growth provides crucial forage and pollen for ungulates and pollinator species. Foliage and associated insects are vital spring food for sage-grouse hens and chicks. Biscuitroots are host plants for the Anise swallowtail butterfly and the rare Indra swallowtail butterfly.
