Also known as Diamondleaf Saxifrage and Early Saxifrage, this species can often be found in rocky habitats. This is one potential origin for the genus (and family) name, as "saxifrage" is translated to mean "rock-breaker;" another potential origin, as discussed by Gerard in The Herbal (1633), is that plants in this family have been used for hundreds of years to treat kidney stones (Weber 1976; Southwest Colorado Wildflowers).
