Discussion

Reports of Artemisia frigida from eastern Canada (Ontario eastward), the eastern United States (e.g., Connecticut, Massachusetts, Michigan, Vermont), and Arkansas and Missouri appear to be from old garden sites where the plants may persist. The similarity of this native species to cultivars from eastern Asia (especially Siberia) has led to a number of reports that are apparently based on other cultivars. As a plant with attractive silver foliage, this species has good potential as a drought-hardy plant for flower gardens in cold climates.
