[1][2] Crocidium is native to western North America: British Columbia Washington, Idaho, Oregon, and California.

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.
