[1][2] Crocidium multicaule is a small annual, typically not exceeding 30 centimetres (12 in) in height when in flower.

It grows from a low small patch of somewhat fleshy leaves at the ground and erects several tall thin stems, usually with reduced leaves on the lower part of the stem, and topped by a single flower head.

The flower head is made up of five to 13 (usually 8) 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.
