Shrub of the Cistaceae family, the sage-leaved rockrose is one of the most widespread species of the genus in the Mediterranean basin, present from the Iberian Peninsula to Turkey and North Africa, with a large representation in southern France, Corsica, Italy, and the Mediterranean islands. It occupies open garrigues, degraded maquis, rocky slopes, the edges of pine forests, and sunny embankments, on various substrates, acidic or calcareous, from sea level up to about 800 meters altitude.
It is a low and spreading shrub, reaching 30 to 60 centimeters in height, often wider than tall, forming dense and well-branched clumps. The leaves are oval, wrinkled, and crinkled like those of common sage, which gives it its epithet, grayish-green on the upper side and whitish and tomentose below, slightly aromatic when crushed.
The flowers are pure white, with five delicately crumpled petals, without a basal spot, centered with a cluster of bright yellow stamens. At the peak of flowering, they literally cover the foliage to the point of almost completely concealing it, transforming the clump into a dome of immaculate white highlighted only by the small yellow hearts. This floral generosity is one of the most striking features of the species, noticeable from the first photograph.
In its natural habitat, its flowering extends from March to June. In cultivation, it can begin as early as February in the mildest regions.
In cultivation, it adapts to most well-drained, dry soils, in full sun. Relatively hardy for a rockrose, it tolerates frosts down to about -12°C in draining soil.
