Characteristics:

Roezl's penstemon is a moderate-sized, several stemmed wildflower. Its flowering stems are often up to 50 cm tall. It is slender in appearance, and often is found sprawling near the ground. The leaves are primarily found on the stems, although some sterile, leafy shoots may be found at the base. The leaves are linear to oblanceolate in shape, tapering to a point. The leaves are entire, and often folded at the midrib on the upper leaves. The upper leaves are sessile and somewhat clasping. Leaf length is from 2 to 7 cm. The stems may be green or purplish in color, and hairy below to glandular above.

The inflorescence is a raceme-panicle. The corolla is a bright blue to blue-violet or even purple with a lighter throat. The corollas are 1.4 cm to 2.2 cm in length. The corolla is definitely two-lipped, the lips moderately spreading. The corolla is glandular outside, smooth inside. The anthers are horseshoe-shaped. The plant is similar to Cheerful Penstemon, P. laetus var. sagitattus, but the flowers are smaller, and the anthers of a different shape.


Habitat:

Roezl's penstemon is found in dry, rocky or gravelly slopes and flats. It is often found associated with sagebrush, juniper, and ponderosa pine.


Range:

Roezl's penstemon is found from the central Oregon's Wheeler County south through eastern Lake County, westward towards southwestern Oregon, and south into northern California.
