Petrorhagia Overview

Members of this genus of annual and perennial flowering plants are native to the Mediterranean and other parts of Eurasia and are in the Caryophyllaceae family of carnations. Some species have naturalised in regions where they have been introduced as garden specimens. They have narrow, almost grass-like foliage and clusters of starry flowers similar to those of the related Dianthus genus, in shades of pink, pale purple or white. In cultivation they are popular rock garden plants.
