About Campanula scabrella Engelm.
Campanula scabrella Engelm. is a bellflower species with the common name rough bellflower. It is native to the mountains of the western United States, where it grows in talus and other rocky alpine habitats. This tough perennial herb grows in a clump from a woody rhizome, and rarely exceeds 5 centimeters in height. Its stiff leaves are linear to narrowly oval in shape and about 3 centimeters long, and they are borne on winged petioles. The leaves are covered in very short, appressed pale hairs. The small funnel-shaped flower is just under a centimeter long, and pale blue or lavender in color. It grows from the leaf clump on an erect pedicel about a centimeter tall. Campanula scabrella has three known disjunct ranges: a core range in the mountains of central Idaho and western Montana, the Cascade Mountains of Washington, and northern California on and around Mount Shasta and Mount Lassen. It grows in scree and talus on or near mountain tops and ridges.
