Penstemon deustus
Also called Hot Rock Penstemon, Hotrock Beardtongue, Scabland Beardtongue
Scabland penstemon is a small, partly woody perennial subshrub native to the dry, rocky northwestern United States, grown in gardens and revegetation projects for its drought tolerance and pollinator-attracting flowers. It needs sharp drainage and full sun, and it resents heavy watering and rich soil.
Penstemon deustus is a species of penstemon known by the common names hotrock penstemon and scabland penstemon. It is native to much of the northwestern United States from the Pacific Northwest to Wyoming, where it grows in many types of forest and open plateau habitat, often on soils heavy in volcanic rock or on limestone outcrops.
Penstemon deustus has a range that extends over parts or most of eight western US states. It grows in much of Eastern Washington and all but the northwest corner of Oregon. It also grows in California to the north of San Francisco Bay in the North Coast Ranges into the Klamath Range and Cascades. They also may be found in the northern and central Sierra Nevada. It is very widespread in Nevada, being recorded in every county except for Lincoln County. Similarly it is found in much of Idaho. However it is only known from two southwestern counties of Montana, three western counties in Wyoming, and just Box Elder County in northwest Utah.
This plant is used in wilderness revegetation and landscaping projects in its native region. It is favored for its low water needs and its abundant flowers which attract pollinators, including honey bees, bumblebees, sweat bees, and leafcutter bees.
