Campanula petiolata
Campanula petiolata is a flowering plant that is called western harebell when it is distinguished from Campanula rotundifolia or simply harebell when it is considered the same species. It is in the bellflower family (Campanulaceae). This herbaceous perennial is found in areas of western North America with continental climates. It produces violet-blue, bell-shaped flowers in late summer and autumn. It is closely related to Campanula rotundifolia and is considered either a subspecies or the same species by many botanists.
The western harebell is rhizomatous, forming a clump of plants and tends to have more of this character when growing in sunny conditions.
Plants of the world online records Campanula petiolata as growing in the far north of Canada in Nunavut and the Yukon southwards to the United States west of the Dakotas, Colorado, and Texas. The southern limit of its range extends into north east of Mexico. In the Pacific Northwest they are unevenly distributed from sea level to approximately 1900 meters in elevation. In the Southern Rocky Mountains they are often found on grassy hillsides, in lodgepole pine forests, along road cuts in montane ecosystems from the foothills to the timberline. In northern Mexico it grows in three states, Chihuahua, Coahuila, and Nuevo León. Campanula petiolata will grow in relatively dry areas in the mountains or in medium (mesic) soils, but require well drained gravely or sandy soils if conditions have more moisture.
