Townsendia is a genus of North American plants in the tribe Astereae within the family Asteraceae.[2][3]
The genus is known commonly as Townsend daisies or as grounddaisies.[4][5] 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.[6]
The genus name honors Pennsylvania botanist David Townsend (1787–1858).[2][6]
