About Dune Tansy (Tanacetum bipinnatum) 8 Nurseries Carry This Plant 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.
