"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 inflorescence, which can approach a meter in height. It is coated in soft white hairs. The flower head at the top is up to 4 centimeters wide and lined with reddish or purplish green phyllaries with curling tips. The head is ligulate, containing many yellow ray florets and no disc florets. The fruit is an achene which may be nearly 3 centimeters long, including a long beak and long white pappus.
