Tanacetum bipinnatum

Dune Tansy (Tanacetum bipinnatum) is a native perennial herb in the Asteraceae (Sunflower) family that grows in Central and Northern California, primarily in the North Coast and Central Coast regions. It grows from a rhizome. The leaves are lacy and ferny. The inflorescence bears up to 15 flower heads, each about a centimeter wide. Each head contains many yellowish disc florets and many pistillate florets around the edges. The latter may have minute ray florets. The fruit is an achene a few millimeters long which is tipped with a small pappus of toothed scales. It tends to grow at elevations from 0-1,000 feet, primarily in Coastal Strand habitat. It is hairy, glandular, and aromatic, with a camphor-like scent.
