About Agoseris grandiflora (Nutt.) Greene
Agoseris grandiflora is a perennial herb that grows a basal patch of leaves with varied shapes, which reach a maximum length of 50 centimeters. Most often, the plant has no stem, but a rudimentary stem may sometimes develop. The upright visible portion of the plant is actually the inflorescence’s peduncle, which can grow close to one meter in height. The entire plant is covered in soft white hairs. The flower head at the top of the peduncle is up to 4 centimeters wide, and lined with reddish or purplish green phyllaries that have curling tips. This is a ligulate flower head: it holds many yellow ray florets, and contains no disc florets. The fruit produced is an achene that can measure nearly 3 centimeters long when including its long beak and long white pappus. This species grows in meadows and forest openings.
