An extremely variable, leafy plant ranging from spindly and tiny to large and bushy, with yellow bilaterally symmetrical flowers on slender stalks in upper leaf axils. Seep monkey-flower or golden monkey-flower grows as an annual or perennial and is known for its spikes of snapdragon-like flowers topping leafy, 2-3 ft. stems. The bright-yellow flowers, spotted with purple on the lower lip, appear against soft, light-green, broadly rounded and toothed leaves.

In this large genus of several look-alikes with yellow corollas, Common Monkeyflower is distinguished by the longer upper tooth on the angular calyx.
