Diapensia lapponica, the pincushion plant, is a plant in the family Diapensiaceae, the only circumboreal species in the genus Diapensia, the others being mainly in the Himalaya and on mountains in southwestern China. This species likely became circumboreal-circumpolar [Arctic–alpine] after it jumped to arctic habitat from North China and Russia. The most likely candidate for ancestor is a white-flowered D. purpurea The plants grow on exposed rocky ridges that are kept free from snow by high winds. Diapensia lapponica is extremely slow and low-growing and cannot compete with plants that overtop it. The plant is very sensitive to higher temperatures and so is often in misty foggy habitat. It usually dies when transplanted to lowland gardens and so this is not recommended. Cold-treated or wild and winter-collected seed will germinate indoors. The seed and leaves are high in lipids.
Ranunculus glacialis, the glacier buttercup or glacier crowfoot, is a plant of the family Ranunculaceae. It is a 5-10(-20) cm high perennial herb.

Sibbaldia procumbens is a species of flowering plant of the genus Sibbaldia in the rose family. It has an Arctic–alpine distribution; it can be found throughout the Arctic, as well as at higher elevations in the mountains of Eurasia and North America. It grows on tundra and in alpine climates where snow remains year-round, and on subalpine mountain slopes. This is a low, mat-forming perennial herb producing clumps of herbage in rocky, gravelly substrate. A spreading stem up to 15 centimeters long grows from a caudex. Each leaf is divided into usually three leaflets borne at the end of a petiole up to 7 centimeters long. Each wedge-shaped leaflet has three teeth at the tip. The flower has usually five pointed green bractlets, five wider pointed green sepals, and five tiny yellowish petals each about a millimeter long. The fruits develop in the remnants of the sepals on erect stalks.
Artemisia cana is a species of sagebrush native to western and central North America, a member of the sunflower family. It is known by many common names, including silver sagebrush, sticky sagebrush, silver wormwood, hoary sagebrush, and dwarf sagebrush.
Artemisia norvegica is a species of flowering plant in the aster family known by the common names alpine sagewort, boreal sagewort, mountain sagewort, Norwegian mugwort, arctic wormwood, and spruce wormwood. It is found in cold locations in Eurasia and high altitudes and high latitudes in North America.

A slender stem, that branches beyond the midpoint, holding small purple, deep purple, blue-violet, light blue or violet flowers. It is cultivated as an ornamental plant in temperate regions. It is often regarded as a synonym of Iris aphylla, but it has chromosomal and morphological differences, so it may considered to be a parent species instead.
