Perennial hybrid of the Saxifragaceae family, section Porphyrion. This garden hybrid involves Saxifraga iranica, a species native to the mountains of northwestern Iran, crossed with other saxifrages of the same section. It is a cultivar selected for its particularly dense and regular cushion, grown in rock gardens, alpine troughs, or between stones of walls.
The plant forms a tight, hemispherical cushion, only a few centimeters in height, composed of very compact rosettes of small linear to lanceolate leaves, medium green, with margins bearing fine whitish calcareous incrustations deposited by the hydathodes, giving the foliage a very characteristic frosted appearance. This white speckling, visible around the edge of each rosette, is one of the most distinctive features of the cushion outside of flowering.
The flowers, borne almost sessile at the cushion's surface, are remarkably large relative to the plant's size, with five broad and rounded petals. They open pure white, with buds sometimes showing a slight pink tint before blooming; as they fade, they gradually turn pink, creating within the same cushion a range of simultaneous shades, from immaculate white to deep pink. In its natural habitat, its flowering extends from May to June. In cultivation, it generally occurs in April-May.
It requires a sunny to slightly shaded exposure, a very well-drained soil, poor to moderately rich, preferably limestone. It poorly tolerates excess winter moisture at the base. Perfectly suited for alpine troughs and mineral rock gardens.
