Horticultural selection with double flowers of the circumpolar perennial from the Caryophyllaceae family. This form, whose exact selection origin is not precisely documented in the sources consulted, is distributed in specialized alpine plant circuits and appears in the catalogs of several renowned nurseries.
The general habit remains true to that of the type species, with a dense and compact cushion of bright green, ciliated linear leaves, overlapping in tight rosettes, not exceeding a few centimeters in height. Growth remains slow.
The uniqueness of this selection lies in its distinctly double flowers, with numerous bright pink to magenta-pink petals layered in several rows, forming small round and dense pompons that contrast sharply with the dark green cushion. The flowers, larger than those of the type form, are sterile due to the duplication of floral parts, which prolongs their presence on the plant.
In cultivation, its flowering occurs in May-June.
As with the entire group, it requires absolute drainage, lean and mineral soil, full sun exposure, and protection against stagnant winter moisture. Propagation can only be done by division or cuttings, as the sterility of the double flowers excludes any reproduction by seed.
