This rare and threatened species makes its home in the sand dunes and hills of the San Francisco Bay area. Development has seriously impacted its native habitat. Fragrant, four-petaled flowers ranging in color from creamy white to yellow rise up to 18” above dark green foliage in the spring and early summer. Thrives with good drainage and occasional water once established. Plant this special wallflower in full sun with other small perennials such as buckwheats, checkermallows and coyote mint. Attractive to butterflies.
