Description
Agoseris glauca 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.[3]
There is no stem but the plant flowers in a stemlike inflorescence 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 but no disc florets.[3]
The fruit is an achene with a body up to a centimeter long and a pappus which may be almost 2 centimeters in length.[3]
