Western Blue Flag
Alberta Home
Western blue flag was first discovered in Alberta in 1964 from two locations in the southwestern corner of the province. Since then, five additional native locations have been discovered together with five locations where the
species has evidently been introduced. Native locations are restricted to the extreme southwestern edge of the province, the most floristically diverse portion of Alberta. This area has been described as a "botanical watershed" that runs
east-west across the Rocky
Mountains.
