A single species from the Caucasus to Iran, P. stylosa, mat-forming, with whorled leaves, with pink-flowers and sometimes a foxy smell. The species epithet stylosa refers to the protruding styles in each flower.
The rounded heads of small tubular flowers are much visited by bumblebees and hoverflies, and if you are lucky hummingbird hawk-moths, while the creeping growth helps conserve water and provides shelter and refuge for invertebrates, including beneficial predators such as ground-beetles. In addition, being related to bedstraws, the leaves could be used as larval food-plants by hummingbird hawk-moths. Phuopsis is increasingly being found in the wild, although the habitats it tends to be found in, including walls and brownfield sites, are not the most natural.
