Agoseris grandiflora is a species of flowering plant in the daisy family known by the common names bigflower agoseris and grassland agoseris. It is native to western North America from British Columbia to California to Utah, where it grows in many habitat types. This is a perennial herb producing a basal patch of leaves of various shapes reaching maximum lengths of 50 centimeters. There is usually no stem, but there is sometimes a rudimentary one. The upright part of the plant is actually the peduncle of the flower cluster, which can approach a meter in height. It is coated in soft white hairs.
