Sorry to quibble, Todd, but Campanula uniflora would not be confused with Campanula rotundifolia. (You may be thinking of Campanula lasiocarpa, on which the flowers are similar to C. rotundifolia?)

According to Flora of Alberta (Moss and Packer), C. uniflora occurs on alpine slopes. Its range is circumpolar, from NE Siberia, Greenland, and northern Europe to Alaska, Yukon to Ellesmere Is. to northern Quebec, Labrador, and Hudson's Bay and south to Montana and Colorado.

This is another bellflower that is only of interest to the avid collector of Campanula. It is hardy to zone 1! The diminutive plant throws up a single, oversized bell that, in shade, is nearly the same as those of the common harebell, C. rotundifolia.
