[edit] Distribution
This wallflower has a circumpolar distribution (northern Greenland westward to North European Russia). It is widespread in the Canadian Arctic Archipielago, and common in Greenland, Norwest Canada and United States (Alaska).
[edit] Ecology
This species seems to be apomictic, since it is scarcely visited by insects and seed production is independent on flower visitors (Kevan 1972b). Nevertheless, more studies are needed on this topic.
