An interesting and rarely cultivated native perennial that grows in grasslands and meadows in central to northern California and the Sierra Nevada foothills. Narrow leaves emerge in the spring giving way to lovely 4 ft. tall flowering stems topped with umbels of delicate white flowers in the summer. Looks particularly nice in mass and livens up a meadow or grassland planting that may be waning in summer. Yampah was an important food source for native people. The habitat gardener can entice the anise swallowtail butterfly with a NATIVE larval food source rather than the ubiquitous non-native fennel. Plant in full sun with a little water. Allow to go dry after flowering.
