Dianthus barbatus, the sweet William,[http://www.thompson-morgan.com/flowers/flower-plants/perennial-and-biennial-plants/sweet-william-sweet/t47479TM Thompson and Morgan plant catalog spelling – Sweet William] is a species of flowering plant in the family Caryophyllaceae, native to southern Europe and parts of Asia. It has become a popular ornamental garden plant. It is a herbaceous biennial or short-lived perennial plant growing to 13–92 cm tall, with flowers in a dense cluster of up to 30 at the top of the stems. Each flower is 2–3 cm diameter with five petals displaying serrated edges. Wild plants produce red flowers with a white base, but colours in cultivars range from white, pink, red, and purple to variegated patterns. The exact origin of its English common name is unknown but first appears in 1596 in botanist John Gerard's garden catalogue. The flowers are edible and may have medicinal properties.{{Citation needed|date=August 2012}} Sweet William attracts bees, birds, and butterflies.

Many legends purport to explain how sweet William acquired its English common name, but none is verified. It is often said to honour the 18th century Prince William, Duke of Cumberland. As a result of the Duke's victory at the Battle of Culloden and his generally brutal treatment of the king's enemies, it is also claimed that the Scots sometimes call the flower "stinking Billy".Meyer, D. (1987). The Highland Scots of North Carolina, 1732–1776, p. 14. Univ. N. Carolina PressHairr, J. (2002). Harnett County: A History, pp. 23–24. Arcadia PublishingRoss, D. R. (2001). On the Trail of Bonnie Prince Charlie, p. 112. Dundurn Press Though this makes a nice story, it is entirely untrue. The Scots sometimes refer to the noxious ragwort as stinking willy in memory of the infamous Duke. Phillips speculated that the flower was named after Gerard's contemporary, William Shakespeare.Phillips, H. (1829). Flora Historica, p. 43. E. Lloyd & Son It is also said to be named after Saint William of York or after William the Conqueror. Another etymological derivation is that william is a corruption of the French oeillet, meaning both "carnation" and "little eye". Sweet William is a favourite name for lovelorn young men in English folkloric ballads, e.g., "Fair Margaret and Sweet William".

Sweet William is a popular ornamental plant in gardens, with numerous cultivars and hybrids selected for differing flower colour, ranging from white, pink, red, and purple to variegated patterns.

The plant was introduced to northern Europe in the 16th century, and later to North America and elsewhere, and has become locally to widely naturalised in these areas.Missouriplants: [http://www.missouriplants.com/Redopp/Dianthus_barbatus_page.html Dianthus barbatus] {{Webarchive|url=https://web.archive.org/web/20131217011409/http://www.missouriplants.com/Redopp/Dianthus_barbatus_page.html |date=2013-12-17 }}

John Gerard praises its beauty but omits any reference to medicinal uses. Its height makes it convenient for flower arrangements. In the Victorian language of flowers, sweet william symbolizes gallantry. The plant is widely used in borders, rock gardens and informal country cottage style gardens. Sweet William is a good candidate for a naturalistic garden because its nectar attracts birds, bees, and butterflies. Its flowers are considered edible.{{Citation needed|date=January 2019}}

Sweet William is a species of Dianthus.

It thrives in loamy, slightly alkaline soil with sun to partial shade. Propagation is by seed, cuttings, or division, but seeds of cultivars will not breed true. If it is planted from seed after the last frost, it will flower in the second year. If it is planted in flats before the last frost and then transplanted, it may flower in the first year. Some gardeners recommend deadheading to encourage further flowering. The plant is self-seeding.Crockett, J.U. 1961. Greenhouse gardening as a hobby. Doubleday & Company, Inc., Garden City, New York. Sweet William can suffer from Fusarium Wilt which causes the leaves to curl or droop down.{{Cite web|url=https://horticulture.ahdb.org.uk/download/8433/file|title=Horticulture | AHDB|access-date=2019-01-28|archive-date=2019-01-24|archive-url=https://web.archive.org/web/20190124152403/https://horticulture.ahdb.org.uk/download/8433/file|url-status=dead}}

In 1977, the question of possible medical uses was revisited by Cordell. Saponins were found in Sweet William, but there has been little follow-up.Cordell, G. A., Lyon, R. L., Fong, H. H., Benoit, P. S., & Farnsworth, N. R. (1977). Biological and phytochemical investigations of Dianthus barbatus cv." China Doll"(Caryophyllaceae). Lloydia, 40(4), 361-363.

At the wedding of Prince William and Catherine Middleton on 29 April 2011, Catherine Middleton included Sweet William in her bouquet, a tribute to her bridegroom.{{Cite web|url=https://www.express.co.uk/life-style/life/962301/Meghan-Markle-royal-wedding-kate-middleton-bouquet-flowers-compared|title = Meghan Markle v Kate Middleton wedding bouquet: Meaning of both brides' flowers compared|date = 19 May 2018}}
