The genus is known commonly as Townsend daisies.[4] 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.[5]

The genus name honors Pennsylvania botanist David Townsend, 1787–1858.[2][5]
