Erythranthe purpurea is a petite annual herb growing just a few centimeters tall. The oppositely arranged oval leaves are under 2 centimeters long each. Each flower is borne on a very thin, erect pedicel which may be several centimeters tall.

The tubular base of the flower is encapsulated in a reddish ribbed calyx of sepals with tiny pointed lobes. The flower is roughly a centimeter long with a wide mouth divided into an upper and lower lip. The flower is pink, the upper lip usually a darker shade than the lower, and there are yellow stripes or streaks in the mouth.
