Agoseris glauca
is a species of flowering plant in the daisy family known by the common names pale agoseris and prairie agoseris. It is native to northern and western North America from Alaska to Ontario to New Mexico, where it grows in many habitat types. This is a perennial herb which varies in general appearance. It produces a basal patch of leaves of various shapes which may be as long as the plant is high. There is no stem but the plant flowers in a stemlike flower cluster which is sometimes erect, reaching heights near half a meter or taller. The flower head is one to three centimeters wide with layers of pointed phyllaries. The head is ligulate, bearing many yellow ray florets and no disc florets. The fruit is an achene with a body up to a centimeter long and a pappus which may be almost 2 centimeters in length.
