The Western coneflower (Rudbeckia occidentalis) belongs to Asteraceae (the Aster family). It is a perennial herb that is native to the northwestern United States, from Washington to northern California and east to Wyoming and Montana. This herb grows in wet meadows, seeps, along streams, at pond edges, and up to a height of 60-200 cm. The leaves are widely ovate, with short rough hairs on both sides or just the underside. The flower-heads bloom in late summer. They have dark purple-brown disk cones about 2.5 cm high, no ray flowers. The cones become twice as tall and black when in seed.
