Hmm, I suppose that that common name, "inflated oxytrope", like bladderpod, is not likely to hold much appeal for the gardening public! Oh well.
Oxytropis podocarpa is probably one of the most distinctive alpine oxytropis in this area, due to its very finely divided leaves and for its colourful seed pods. Its purple flowers fade attractively to blue. It is quite common and can blanket fairly large areas, in suitable habitat - that being "exposed rocky ridges and turfy alpine hillsides" (Moss & Packer, Flora of Alberta).
