2n=16*, 32 (Moss, 1983). Also known as ssp. kamachatica (Moss, 1983). Rock cresses have been eaten but this species especially has been known to have a good taste; Inuit of Alaska ate leaves raw or cooked; they fermented them for used in the winter; this species has been classified as rare in some regions so it is best to not consume (Johnson et al., 1995). Also known as Arabadopsis lyrata (E-Flora BC; JSTOR).
