A rare species native to sand dunes along the north coast of California. Forms tight mounds of narrow leaves 8-12 inches tall and wide. Bright-yellow fragrant flowers bloom in late spring and will continue into summer with a little additional summer watering. The fragrant flowers are butterfly favorites. Adaptable and can seed about if happy, though not weedy. Requires good drainage, full sun, to light shade inland, with moderate to occasional summer water. Said to be deer tolerant.
