Minuartia sedoides, also known as rock sandwort or rock-loving sandwort, is a species of flowering plant in the family Caryophyllaceae. It is native to North America, and it is found in rocky or gravelly soils in alpine and subalpine environments, such as cliffs, talus slopes, and scree fields. Rock sandwort is a small, mat-forming perennial plant with thin, needle-like leaves and small, white flowers that bloom in the spring. It is adapted to dry, rocky environments, and it is often found in areas with low soil moisture and nutrient levels. In traditional medicine, Minuartia sedoides has been used to treat a variety of ailments, including respiratory problems, digestive issues, and skin irritation. However, there is little scientific evidence to support these uses.
