Scouler's harebell is an interesting perennial wildflower with one to several lax stems from 10-40 cm long. The herbage is glabrous, or occasionally with a few small short hairs. The leaves are alternate on the stems and are all petiolate with serrate margins. The lower leaf blades are ovate to rotund-ovate in shape and range from 1-4 cm long. The petioles of the lower leaves are equal to or greater in length than the blades. The upper leaves are are narrower with shorter petioles, becoming reduced to sessile, linear bracts.
The inflorescence consists of several nodding flowers on slender, elongated pedicels. The corollas are pale blue to whitish, ranging from 8-12 mm long with ovate-oblong petals which often bend backwards. The style extends well past the corolla (See photo above.).
Scouler's harebell may be found in open to fairly dark woods and occasionally on talus or rock outcrops at low to moderate elevations.
Scouler's harebell may be found from the Alaskan panhandle south through the Pacific Northwest to northern California and east to the eastern slopes of the Cascade Mountains.
In the Columbia River Gorge it may be found between the elevations of 100'-4000' between the Sandy and White Salmon Rivers.
