Sweet™ Scarlet Dianthus is an upright Sweet William selection with single-petaled scarlet flowers and sturdy stems. Its blooms are described as long-lasting and fragrant, making the plant useful in sunny garden displays as well as cut-flower beds. [The exact Sweet™ Scarlet page](https://info.ballseed.com/webtrackplantinfo.aspx?ENV=P&phid=022502007004940) identifies selection code PAS426635. ## Garden and cutting use The listed mature size is 18–36 inches tall and 10–12 inches wide. Plant it in full or partial sun in a border, or group it in a cutting garden where its straight stems are easy to reach. Ball Seed lists the selection for USDA hardiness zones 6a–8b. ## Growing conditions The breeder lists light water needs. [NC State Extension’s Dianthus barbatus profile](https://plants.ces.ncsu.edu/plants/dianthus-barbatus/common-name/sweet-william/) recommends well-drained soil and notes that partial shade can help in hot-summer climates. Good drainage matters because poorly drained conditions can contribute to crown rot. ## Maintenance Water lightly in response to rainfall and soil conditions, avoiding persistent saturation. Remove faded flower stalks to tidy the planting or harvest stems for fresh arrangements.
