Erigeron maniopotamicus
Also called Mad River Fleabane Daisy
Mad River fleabane is a rare daisy-family wildflower found only in northwestern California, growing in open, rocky, barren ground near the Mad River. It is a wild species with no established garden cultivation, so the key to any care is respecting its need for sun and sharp drainage.
Erigeron maniopotamicus is a rare species of flowering plant in the family Asteraceae known by the common name Mad River fleabane. It is endemic to northwestern California, where it is known from only nineteen locations in Humboldt and Trinity Counties.
Erigeron maniopotamicus grows in open areas in forest, woodland, and meadow habitat along the path of the Mad River, generally in barren areas without much plant cover. The soils are rocky and tan in color and occur near areas of serpentine soils, but the plant does not occur on the serpentine soil.
