Erysimum pallasii, or Pallas' wallflower, is a low shrub or mid shrub species from the Arctic. It has purple flowers that do not reflect UV.^[1]

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).

Ecology

This species seems to be apomictic, since it is scarcely visited by insects and seed production is independent on flower visitors.^[2] Nevertheless, more studies are needed on this topic.
