Phuopsis stylosa

Perennial of the Rubiaceae family, Phuopsis stylosa is native to the Caucasus, northern Iran, and adjacent regions. It naturally grows on rocky slopes, screes, and open edges, at mid to high altitudes.

It forms spreading clumps, even loose carpets, reaching 15 to 25 cm in height, with slender, branched stems bearing narrow, lanceolate leaves, whorled in groups of six to eight, of a medium green. The foliage emits a strong and characteristic odor, sometimes described as musky or fox-like, noticeable with a simple crush.

The flowers are tiny, tubular, gathered in terminal globular heads of bright pink to deep pink-lilac, with a very prominent style that gives the inflorescence a recognizable bristly appearance. In its natural habitat, flowering extends from June to August. In cultivation, it generally occurs from May to July, with sometimes a partial resurgence.

It adapts to most well-drained soils, in full sun, and tolerates drought once established. Used as ground cover on embankments, walls, or rock garden borders, it readily reseeds and can become invasive in suitable conditions.
