Saxifraga is the largest genus of the Saxifragaceae family with roughly 440 species spread around temperate regions of the northern hemisphere. The latin name means stone breaking which could refer to many species growing in rock crevices at high altitudes. Other species are larger and grow on moist meadows, but most species, even those growing on cliffs, grow where there is some moisture. A few species are native to Iceland.
