The genus is known commonly as Townsend daisies or as grounddaisies. These annual, biennial and perennial wildflowers are native to western North America, frequently at high elevations. A number of taxa are tall, erect plants, like typical daisies. Others form small, dense, leafy rosettes, or have a more sprawling, prostrate appearance. Frequently, the flower heads are showy and attractive, with the ray florets in shades of pink, purple, blue, white, and, rarely, yellow.
The genus name honors Pennsylvania botanist David Townsend (1787–1858).Flora of North America, Vol. 20 Page 193 Townsendia Hooker, Fl. Bor.-Amer. 2: 16, plate 119. 1834.
