dune tansy
Native to sand dunes from the Bay Area north, this shrubby evergreen groundcover spreads quickly to create drifts of soft fern-like foliage. Yellow, button-shaped flowers form small clusters atop stalks up to 2 ft. tall. Enjoys full sun to light shade. Tolerant of clay soils and excessive moisture but will thrive with only occasional water once established. Reducing irrigation can temper this tansy's somewhat aggressive nature. Dune tansy has a strong scent of camphor and is valued for its medicinal uses. Beautiful when combined with ceanothus, Douglas iris and other plants from our coastal areas. Good for erosion control.
