Another of the encrusted saxifrages, this one has relatively small, silvery rosettes and 4-8" flower stems topped with a loose spray of pure-white flowers. This species hails from limestone regions pf the SW Alps between France and Italy. There are several named forms which differ on the size of the rosettes. The cultivar 'Minor' has very small, crowded rosettes and 4" flower stems. It's a gem for an alpine trough.
