Bouncing Bet Soapwort Seeds – Fragrant Perennial Wildflower, Medicinal Herb (Saponaria officinalis)

Saponaria officinalis, commonly known as Bouncing Bet or Common Soapwort, is a charming and fragrant perennial wildflower from the carnation family (Caryophyllaceae). Native to Europe and widely naturalized across the eastern United States, it blooms throughout summer with clusters of delicate white to soft pink 3/4" flowers that are lightly fragrant in the evening — a vespertine bloomer that perfumes the garden at dusk. Spreads vigorously by creeping rhizomes, making it an excellent low-maintenance ground cover, border filler, or naturalized wildflower planting.

About Bouncing Bet

Soapwort has a long history as both an ornamental and a functional plant. Its roots and leaves produce a natural lathering soap substitute when crushed in water — historically used for washing delicate textiles and as a gentle cleansing agent. As a medicinal herb, it has traditionally been used as an expectorant. Note: roots and seeds are considered toxic if ingested — handle with care and keep away from children and pets.
