Comments: Plains Blackfoot Daisy is an excellent landscape species for a natural look in rock landscapes and other arid gardens. Plains Blackfoot Daisy is easily confused with Desert Zinnia, Zinnia acerosa which also has white and yellow daisy-like flowers. The differences are not always clear but one difference is Desert Zinnia has fewer ray flowers 4 to 6, versus 8 to 10 on Plains Blackfoot Daisy.
The common name "Blackfoot" is a reference to the black color at the base of the stem and roots. Also see Shaggy Blackfoot, Melampodium strigosum.
