Description: The flower is a 1 to 1 1/2 inch two-lipped tube, the upper lip divided in two, the lower in three. The lower lip has two whitish landing strips with faint purple veins. The stamens hug the inside walls of the tube allowing bees easy entry.

Habitat: Exposed rocky slopes and summits.

Comments: The flowers of this penstemon are "showy" not only for their large size, but for their dazzling color. Watch bees disappear into the flower tube to probe for nectar.
