Saxifraga, commonly called Saxifrage or Rockfoil, is a large genus of about 400 species of perennials in the family Saxifragaceae, native to temperate, subarctic and alpine areas of Europe, Asia and North America.
This plant produces fine-textured foliage and small bright flowers, usually with five petals, five sepals and ten stamens. Saxifrages are great for rock gardens, containers or along retaining walls.

Some believe the name refers to its ancient medicinal use for treating urinary stones.
The common name “Rockfoil” comes from its preference for a rocky environment.
