Native to the European Alps, this evergreen herbaceous perennial is a member of the mustard family, Brassicaceae, that also includes cabbage, alyssum, and stock. The tufted compact plants grow 1-6″ tall and have lanceolate, gray-green toothed leaves. From spring until summer, elongated clusters of pale yellow slightly fragrant flowers appear. This species of Erysimum is more perennial than other members of the genus and is valued for borders as well as rock, scree, wall, alpine, and container gardens. The genus name, Erysimum, is from the Greek word eryo meaning to drag . The specific epithet, pumilium, is the Latin word meaning dwarf and refers to the size of the plant.
