Agoseris is a small genus of annual or perennial herbs in the family Asteraceae described as a genus in 1817.[1][2]
Agoseris is native to North America, South America and the Falkland Islands.[3][4]
In general appearance, Agoseris is reminiscent of dandelions and are sometimes called mountain dandelion or false dandelion. Like dandelions the plants are (mostly) stemless, the leaves forming a basal rosette, contain milky sap, produce several unbranched, stem-like flower stalks (peduncles), each flower stalk bearing a single, erect, liguliferous flower head that contains several florets, and the flower head maturing into a ball-like seed head of beaked achenes, each achene with a pappus of numerous, white bristles.
