This plant bears pretty pink blossoms for a few months of the year, and foliage is also attractive throughout the season! The roots and leaves of some species of Saponaria have been used as a soap since the Renaissance, which is the reason these plants are called soapwort! Museum conservators still use the soap for cleaning delicate fabrics not able to withstand modern soaps! This makes a great nursery plant for areas where other, slower growing groundcovers are to be grown. It spreads very rapidly, preventing weeds while new plants are establishing!
