Dart™ White is an upright, compact Sweet William with white flower clusters. PanAmerican Seed identifies this Dianthus barbatus selection as PAS1514687 and lists a mature size of 6–12 inches high by 6–8 inches wide. ## Garden use White flowers bring a clear accent to a small border, patio container or cut-flower bed. Ball describes Dart as compact, suited to different pot sizes and able to perform in cooler garden conditions without staking in beds. Like other Sweet Williams, it is a biennial or short-lived perennial often grown as an annual for seasonal color.

In hot-summer areas, partial shade can suit the species; avoid wet soil around the crown. The supplier lists flowering periods from early spring through summer and autumn, but the actual outdoor display follows local climate and planting time.

Deadhead spent flower heads when needed to keep the plant tidy or reduce self-sowing. Dart's compact habit generally does not need staking in a garden bed.
