Perennial of the Lamiaceae family, native to southern and central Europe, from Spain to the Balkans and western Anatolia, where it grows on rocky grasslands, calcareous scree, and well-exposed stony slopes, generally between 500 and 2,000 meters in altitude.
It forms a dense and spreading cushion, woody at the base, with short and branched stems, reaching 10 to 20 cm in height. The leaves are small, oval to elliptical, dark green and shiny on the upper side, lighter underneath.
The flowers are creamy white to pure white, distinctly bilabiate, borne in short and compact spikes at the top of the stems, mixed with bracts browning at maturity, giving the flowering plant a delicate yet bushy appearance.
In its natural habitat, its flowering extends from June to August depending on the altitude. In cultivation, it generally blooms in June-July.
It requires full sun and a calcareous, poor, and very well-drained soil, dry in summer. Perfectly hardy, it is suitable for calcareous rockeries, walls, and compositions in the style of garrigue or steppe. Its ability to form a compact and flowering cushion makes it a reliable subject for hot and dry situations.
