About Penstemon roezlii Regel
Penstemon roezlii Regel, a species of penstemon, is commonly known as Roezl's penstemon. It is native to Oregon, western Nevada, and adjacent areas of northern California—including the Klamath Mountains and Sierra Nevada—where it grows in sagebrush and forest habitats. This is a hairy, erect perennial herb that grows from a woody, branching base, reaching a maximum height of 55 centimeters. Its leaves are up to 7 centimeters long, shaped from linear to widely lance-shaped, and often folded along their length. Its glandular inflorescence produces wide-mouthed tubular flowers up to 2.2 centimeters long, which occur in blue-purple shades. The flowers are mostly hairless, apart from thin glandular hairs on their outer surfaces.
