History
Centaurea moschata, the sweet sultan or royal sweet sultan, now often treated as Amberboa moschata, is an upright annual native to the eastern Mediterranean, Turkey, and Iran. The plant was cultivated in Ottoman imperial gardens and reached western Europe via Constantinople around 1620. English herbalist John Parkinson described it enthusiastically in his 1629 Paradisi in Sole Paradisus Terrestris, praising the sweet-musk fragrance of the fluffy fringed flower heads in white, yellow, pink, and purple.
Sweet sultan remained a cottage garden staple through the Victorian era and is still valued as a long-lasting fragrant cut flower. Seed mixes including The Bride and Imperialis Giants continue to be sold by heirloom seed suppliers. The plant thrives in cool weather and deep well-drained soils and self-seeds gently.
Introduced from Turkey to European gardens in 1629 and to American colonial gardens by the 1700s. A favorite of Thomas Jefferson at Monticello, recorded in his 1767 garden notebook. Modern cut-flower specialists like Floret Farm have revived Sweet Sultan for farm-to-florist American cottage garden sales.
