The Cascades penstemon (Penstemon serrulatus) belongs to Scrophulariaceae (the Figwort family). It is a perennial herb that is native from British Columbia south to Oregon in the United States. This herb grows in moist meadows, along streams, rocky areas, from near coast to subalpine, and it can reach 20-75 cm in height. The stems are upright and unbranched. The leaves are ovate to lanceolate with sharp toothed edges. The lower leaves have short petioles and the upper cauline leaves are clasping. The trumpet-shaped, bright blue to purple-blue flowers bloom in the clusters atop the stem in mid summer.
