Agoseris grandiflora is a North American species of flowering plants in the daisy family known by the common names California dandelion, bigflower agoseris, and grassland agoseris.[2]
The plant is native to western North America from British Columbia to California to Utah, where it grows in many habitat types.[3][4]
Description
Agoseris grandiflora 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.[2]
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.[2]
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 but no disc florets.[2]
The fruit is an achene which may be nearly 3 centimeters long, including a long beak and long white pappus.[2]
