According to W. Harding (Saxifrages: A Gardener's Guide to the Genus), Saxifraga cuneifolia is "widely distributed in the wooded, sub-alpine mountains of southern Europe, extending from the eastern Pyrenees to the Carpathians".

Positive Todd_Boland On Dec 7, 2004, Todd_Boland from St. John's, NL (Zone 5b) wrote:

There are 4 species and several hybrid saxifrages that fall under the Robertsoniana section. The most popular is S. X urbium 'London Pride'. Saxifraga cuneifolia is the smallest member with 1-2" rosettes of small, thick, wedge-shaped leaves which are deep green and often turn bronzy-purple in winter. They produce wiry stems to 8" tall and a loose spray of small, white starry flowers. Part to full shade in a humus-rich soil will keep them happy. It can be used as a groundcover, but is not as suited to this purpose as the other larger members of this group. Lovely plant for the shaded rockery. It is native throughout the mountains of southern Europe, growing as an understory plant in mixed forests.
