Ranunculus glacialis
Also called Glacier Crowfoot
Glacier buttercup is a small, cold-adapted alpine perennial with a single large white-to-pink flower, native to high mountains and Arctic regions. It is not a practical garden plant; it needs cold, gritty, well-drained conditions and cool summers to survive.
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. Often with a single relatively large (1.8 - 3.8 cm) flower, with 5 petals first white later pink or reddish. The underside of the 5 sepals are densely brown-hairy. The leaves are fleshy, shiny, and deeply loped, forming 3 leaflets. Ranunculus glacialis is reported (from Greenland material) to have a diploid chromosome number of 2n = 16.
Ranunculus glacialis is an Arctic–alpine species, found in the high mountains of southern Europe (Alps, Pyrenees, Carpathians, Sierra Nevada) as well as on the Scandinavian peninsula, Iceland, the Faroe Islands, Jan Mayen, Svalbard, eastern Greenland and Finland, where it is endangered and protected.
