Error Report:

The Mountain Harebell, Campanula lasiocarpa, is a very small perennial, leaves are oval, pointed and form a basal rosette. Flowers are violet-blue, bell-shaped. As noted above the plant is nearly all flower.

The two pictures above posted by Daryl definitely are NOT Campanula lasiocarpa. The flowers in those pictures are NOT bell-shaped. The plant is gigantic compared to an actual Campanula lasiocarpa plant. I do not recognise the flowers in those pictures, but they need to be properly identified and moved to the proper classification.

This little bellflower is all flower with minimal basal foliage. It can be found along mountainside trails, growing securely between the rocks. Though small, it is always a pleasant surprise to hikers who visit our Seward, Alaska trails.

This bellflower is native from northern Japan, around the north end of the Pacific to Alaska and the northern areas of the Rockies. It is one of the hardier bellflower species. Not unattractive, but rather simple. It looks like a half-pint version of the common harebell, C. rotundifolia. Probably of more interest to the bellflower collector.
