Saponaria

Saponaria L.

Saponaria in its traditional sense is a genus of ca. 40 species, mainly distributed on mountains of southern Europe and SW Asia. Several species are very handsome for the rock garden (e.g. Walters 1989 and Jäger & al. 2008 for interesting accounts of the genus for Europe).

Saponaria is obviously closely related to Vaccaria and Gypsophila. Molecular studies demonstrated that a small clade of Saponaria is sister to the Gypsophila/Vaccaria clade (Greenberg & Donoghue 2011).
