PYRENEAN WHITLOW GRASS Petrocallis pyrenaica
A rarely-offered alpine plant native to the Pyrenees, Alps and Carpathians, found in limestone screes and rocks. Densely tufted and often cushion-forming, much like a draba. The leaves form rosettes, 4-6mm long. The flowers are four-petalled, 5-8mm across, pale pink or lilac. An ideal rock garden plant!
