Potentilla marinensis, known as Point Reyes horkelia, is a rare perennial herb from the rose family that forms low, dense, scented patches on California's coastal sands. It is a wild native rather than a common garden plant, so it is best grown from seed or stock sourced from native plant nurseries.
