Several 1-2 ft., leafy stems rise from a woody base. The leaves spaced along the stalks are opposite, oval, rather stiff, and with sharp-pointed teeth. One to several whorls of deep blue to purple, tubular flowers are near the top of the flower stalk, bilaterally symmetrical flowers.

This is one of the few penstemons occurring west of the Cascade Range. Serrulatus refers to the little, serrated teeth on the leaves.
