Diplacus fremontii is an annual herb with a thin stem growing 1 to 20 centimeters tall. The oval leaves are up to 3 centimeters long, the ones higher on the plant hairy in texture. The tubular base of the flower is encapsulated in a wide, ribbed, hairy calyx of sepals with pointed lobes. The corolla of the flower is reddish-purple with a darker pink throat with a yellow spot. There are occasionally all-yellow flowers. The flower is one to two centimeters in length.
