 Common Name: Rock Soapwort

Saponaria is a sprawling plant which forms a nice carpet of semi-evergreen foliage. Small sprays of pink flowers appear in early summer. It works well in a rock garden, as a groundcover, or between stepping stones on a path.

The common name, Soapwort, refers to the sap from the roots of S. officinalis which was once used to make soap.

Homeowner Growing & Maintenance Tips:

Saponaria prefers full sun and average to dry, well-drained soil. Cut plants back by about half after they are finished blooming to maintain a compact habit. This may also provide the added benefit of sporadic repeat bloom in late summer.
