Description

Madia elegans is covered with short, stiff hairs. Glands are borne on stalks, especially near the flowers. [1] The showy flower varies in appearance across subspecies and even within subspecies. The leaves grow to 20 centimetres (8 inches) in length. [2] Blooming between April and October, several strongly scented, uncrowded, bright yellow daisy-like flower heads grow at the end of a slender green stem, each typically 3–5 centimetres (1+1⁄4–2 inches) wide. [2] [3] The flower has numerous thin ray flowers, which close at night, [2] and several central disk flowers. It may be solid lemon yellow or have a maroon center. [2] Its fruits are achenes.

Etymology

The foliage of species in the genus has sticky hairs, hence the common name tarweed. [2]

Distribution and habitat

The plant is native to western North America from south-central Washington state to northern Baja California. [3] [1] [4] [5] It may be found in dry open forest, disturbed areas and grasslands from low to high elevations. [3]

Uses

The achenes were historically used as food by Native Americans, including the Pomo and Miwok, who baked them or ground them into flour.
