Dwarf perennial of the Asteraceae family, native to the southwestern United States — Arizona, New Mexico, and neighboring regions — where it colonizes cliff fissures, rocky walls, and mountain scree, generally between 1,800 and 3,000 meters in altitude. Its epithet, from the Latin scopulus, "rock", precisely describes its preferred habitat.
It is one of the most compact fleabanes of the genus: it forms very tight, almost contiguous cushions, only 2 to 5 cm in height, composed of tiny spatulate to oblong leaves, bright green and shiny, barely ciliated on the margins. The density and regularity of the cushion are striking, evoking more certain Saxifraga or Arenaria than the usual fleabanes.
The capitula, borne on very short almost sessile stems, open directly at the level of the foliage. The ligules are white, well developed in relation to the size of the plant, around a bright yellow-orange disc that highlights them with great clarity.
In its natural habitat, its flowering extends from June to August depending on the altitude. In cultivation, it generally blooms in May-June.
It requires perfect drainage, a very mineral and poor substrate, full sun, and protection against any stagnant moisture in winter. It is ideally cultivated in a pot or alpine trough, where the rigor of the conditions can be fully controlled.
