Saponaria calabrica occurs locally in S Italy and through the Balkan Peninsula to W Anatolia. In Greece it is found particularly in Peloponnisos and the W mainland, often gregarious on rocky slopes and gravelly road embankments at low to moderate altitude. In Peloponnisos it often grows mixed with the local Silene integripetala, which is remarkably similar in petal colour and presumably shares the same pollinator.
