Dianthus barbatus, commonly known as Sweet William, is a reliable and long-lived cottage garden favourite, producing dense, flat-topped flower heads in a wide mix of colours. These seeds are ideal for borders, cutting gardens and informal planting, where strong colour and structure are needed in late spring and early summer.
Native to southern Europe, Sweet William has been grown in gardens for centuries and remains valued for its sturdy stems, lightly scented flowers and ease of cultivation. Plants form low rosettes of foliage in their first year, followed by upright flowering stems in the second. Seed-raised plants will produce a varied mix of colours and patterns rather than uniform results.
Best grown in full sun or light shade and well-drained soil, Dianthus barbatus performs well in borders and containers and is particularly effective when planted in groups. It tolerates cooler conditions and is suitable for traditional and contemporary gardens alike.
