Saponaria, commonly known as soapwort, is a genus of flowering plants in the family Caryophyllaceae. These perennial herbs are native to Europe and Asia and are recognized for their pink or white flowers. The name "soapwort" comes from the plant's historical use in making soap, as its leaves contain saponins, which create a lather when mixed with water. The most well-known species is Saponaria officinalis, often found in gardens and naturalized areas. Soapwort thrives in well-drained soil and can grow in various conditions, making it a popular choice for ornamental gardens. Additionally, it attracts pollinators like bees and butterflies, contributing to local biodiversity.
