Saponaria is a genus of flowering plants in the familyCaryophyllaceae, native to Asia and Europe, and are commonly known as soapworts.[2] They are herbaceousperennials and annuals, some with woody bases. The flowers are abundant, five-petalled and usually in shades of pink[3] or white.[2] The genus is closely related to the genus Silene, being distinguished from these by having only two (not three or five) styles in the flower.[3] It is also related to Gypsophila, but its calyx is cylindrical rather than bell-shaped.[4]
The most familiar species might be common soapwort (S. officinalis), which is native to Eurasia but is known in much of the world as an introduced species, often a weed, and sometimes a cultivated ornamental plant.[2] The genus name Saponaria derives from the Latin sapo ("soap") and -aria ("pertaining to"),[2] and at least one species, S. officinalis, has been used to make soap.[5] It contains saponins, and a liquid soap can be produced by soaking the leaves in water.[2] This soap is still used to clean delicate antique tapestries.[6] It is also sometimes stated that it is used as an emulsifier in Turkish delight confections, but this is a case of double confusion. The roots of plants in genus Gypsophila are used to make the Turkish confection helva and Saponaria species are not used.[7]
