Dart™ Red White Picotee Dianthus

Dart™ Red White Picotee is an upright Sweet William with red-and-white picotee flowers. PanAmerican Seed identifies this Dianthus barbatus selection as PAS1514671 and lists a mature size of 6–12 inches high by 6–8 inches wide. ## Garden use Use the bicolor flower heads in a small border, a patio container or a mixed cut-flower bed. Ball describes the Dart plants as compact and says they perform well in cooler garden conditions without staking in beds. Sweet William is a biennial or short-lived perennial, although it is commonly grown as an annual for a planned season of color.

NC State Extension notes that partial shade can be useful in hot-summer climates and warns that poorly drained soil can lead to crown rot. PanAmerican lists flowering windows across early spring, spring, late spring, summer and autumn; these supplier windows are broad and local outdoor timing will depend on climate and planting date.

Deadhead spent stems as needed to keep the planting neat; cut flowers can also be removed for indoor arrangements. The short, compact Dart habit generally stays upright without a support.
