"Soapwort (Saponaria), a genus of plants of the natural order Caryophyllaceæ; so called because the bruised leaves produce a lather like soap when agitated in the water. Common soapwort grows by the roadside in the United States from New England to Georgia.

It has handsome pink-like flowers."—(Charles Leonard-Stuart, 1911)
