Crocidium is a small North American genus of plants in the daisy family.[1][2] Crocidium is native to western North America: British Columbia Washington, Idaho, Oregon, and California.[3]
Crocidium can be found in varied habitats from grassland to woodland. It is a small annual, typically not exceeding 30 centimeters (12 inches) in height. It grows from a small patch of somewhat fleshy leaves at the ground and erects several very tall, very thin gangly stems, each of which is topped with a flower head. The flower head is made up of five to 13 lemon yellow ray florets, each up to a centimeter long. The center of the head is filled with tiny disc florets, in a similar shade of bright yellow. The fruits are fuzzy brown achenes only one or two millimeters long which turn gluey when wet.[4]
