That's its common name. I'm not very good with plants but I have got this information for you:
Saxifraga longifolia, a native of the Pyrenees Mountains. A number of saxifrages absorb mineral-laden water and expel the excess calcium salts to the edges of their leaves, producing an encrusted effect.
Saxifraga longifolia produces solitary foliage rosettes 6" (15 cm) across. Unlike most of its relatives it does not produce offsets. It takes several years to bloom, producing a long (~2' ,or 60 cm) and showy, branched panicle of a hundred or more small white flowers, dying after producing its seeds.
Pops out at you !!!!If I stare at it long enough it appears to move, cool....Maggi
