Dart Red White Picotee dianthus

Dart Red White Picotee is a compact, upright Sweet William with dense flower clusters in deep red edged with white. The crisp picotee pattern gives this selection a clear bicolor accent in small containers and the front of a sunny border. ## Flowers and size [PanAmerican Seed](https://www.panamseed.com/Products/022509905045887/dianthus-dart-red-white-picotee/) identifies the Dart selection as Dianthus barbatus ‘PAS1514671’ and lists a height of 6–12 inches and spread of 6–8 inches. [Thompson & Morgan](https://www.thompson-morgan.com/p/dianthus-dart-red-white-picotee/wkj0620TM) reports a mature height and spread up to 12 inches, so a 6–12-inch range accommodates the differing selection-specific size reports. The breeder notes early flowering relative to the leading red picotee; the retail profile describes a long summer display and flowers suitable for cutting. ## Siting Plant in full sun in fertile, well-drained soil, following the [RHS Dianthus growing guidance](https://www.rhs.org.uk/plants/5729/dianthus-monspessulanus/details). Use it at a border edge, in a patio container, or in a small cut-flower grouping. Its upright stems rise above a compact mound, so close spacing can reduce airflow. ## Maintenance Water regularly through establishment, especially in containers, and avoid waterlogged soil. Deadhead faded clusters to maintain a tidy display and encourage further flowers. Pick stems for arrangements as the lower flowers open.
