Penstemon deustus (Scabland penstemon)

Penstemon deustus

Penstemon deustus Douglas ex Lindl.

Scabland Penstemon, Scabland Beardtongue, Hot-rock Penstemon, Hot-rock Beardtongue

Scrophulariaceae (Figwort Family)


USDA Symbol: PEDE4

USDA Native Status: L48 (N)

The stems grow in clusters from a woody base and have dingy white or cream bilaterally symmetrical flowers in several whorls in axils of leafy bracts. The sub-shrubby branches of this perennial form clumps 8-24 in. high. Its leaves are toothed and bright green, subtending short, whorled clusters of yellowish flowers, marked purple. The flowers are more interesing (at close range) than showy.

In a huge western genus of more than 200 species, this will serve to represent the few with white flowers. Few species of these lovely wildflowers are fragrant, most having a mildly unpleasant odor, especially noticeable in Hot Rock Penstemon.
