Sibbaldia procumbens

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.

It is found in the Pyrenees, in places in the Cantabrians and Sierra Nevada of Spain, in the Alps, the Vosges in France, on Corsica, in a few locations in the central Apennines, in the Tatras on the border of Slovakia and Poland, in Bulgaria's Rila and Pirin.

The plant is also found in extensive areas in some of the Central Asian and South Siberian mountains, including Tian Shan, the Tarbagatay, Altai and Sayan ranges, and the Transbaikal highlands.

It is widely distributed in eastern Kamchatka, in Chukotka, on the Aleut Islands, in parts of Alaska, and then across the constituent ranges of the North American Cordillera in western Canada and the United States, its continuous area reaching its southern limits in the San Bernardino Mountains in California, the San Francisco Peaks in Arizona and the Sangre de Cristo Mountains of New Mexico, with the species reappearing further south at high altitudes in the Transvolcanic Belt of central Mexico.
