Dianthus barbatus L.
Sweet William [Dianthus]
Sweet William is a much-loved cottage-garden plant in the pink family, grown for its dense, flattened clusters of small, fringed flowers in shades of red, pink, white and purple, often with contrasting eyes or patterned markings. It is not a British native but a cultivated species originating in southern Europe and parts of Asia, and it is usually treated as a biennial or short-lived perennial, forming neat leafy clumps before flowering.

About
Sweet William is a much-loved cottage-garden plant in the pink family, grown for its dense, flattened clusters of small, fringed flowers in shades of red, pink, white and purple, often with contrasting eyes or patterned markings. It is not a British native but a cultivated species originating in southern Europe and parts of Asia, and it is usually treated as a biennial or short-lived perennial, forming neat leafy clumps before flowering.
It does best in fertile, well-drained, neutral to slightly alkaline soil in full sun or light shade. Flowering from late spring into summer, its sweetly scented, nectar-rich heads attract bees and butterflies, making it both ornamental and useful to pollinators. It is a classic choice for traditional borders, cutting gardens and informal planting, and the cut flowers are long-lasting in the vase.
