Agoseris glauca is a species of flowering plant in the family Asteraceae known by the common names false dandelion, [2] pale agoseris, prairie agoseris, and short-beaked agoseris. It is native to western North America.
Agoseris glauca is a perennial herb which varies in general appearance. Growing up to 70 centimeters (28 inches), [3] it produces a basal patch of leaves of various shapes which may be as long as the plant is high, [4] but are typically up to 35 cm (14 in). [3]
There is no stem, but from May to September [3] the plant flowers in a stemlike inflorescence which is sometimes erect, reaching heights near .5 metres (1+1⁄2 feet) or taller. The flower head is 1–3 cm (1⁄2–1+1⁄4 in) wide with layers of pointed phyllaries. The head is ligulate, bearing many yellow ray florets but no disc florets. [4] The rays may become pinkish with age. [2]
The fruit is an achene with a body up to a centimeter long and a pappus, which may be almost 2 cm in length. [4]
Other species in the genus known as false dandelion or mountain dandelion, as well as true dandelions, can be distinguished from A. glauca by differences in their fruit. [3]
The plant is native to western and northwestern North America from Alaska east to the Northwest Territories and Ontario, southeast to California, Arizona, and New Mexico. [6] It grows in many habitat types, usually those which are non-forested. [2]
The plant contains a bitter milky juice, which solidifies into a substance that can be chewed as gum; this may have been done by some Plains Indians. [2]
