Dynasty Red Dianthus

‘Dynasty Red’ is a double-flowered, upright interspecific Dianthus in PanAmerican Seed’s Dynasty series, with dark red blooms carried on well-branched, strong stems. PanAmerican lists early-spring, spring, and autumn flowering, first-year bloom, a 16–20-inch height, a 10-inch spread, and perennial performance in USDA zones 6a–9b ([PanAmerican Seed](https://www.panamseed.com/Products/022500476004463/dianthus-dynasty-red/), [Ball Seed](https://info.ballseed.com/PlantInfo/?phid=022500476004463)); a University of Alaska field evaluation also describes the cultivar’s flowers as dark red ([UAF evaluation](https://www.uaf.edu/afes/publications/database/circulars/files/pdfs/C131.pdf)). ## Garden use Use this compact selection in a sunny border or cutting garden. Its upright, strong stems and double flowers suit garden display and cut arrangements, while the 10-inch spread gives it a place among smaller perennials. PanAmerican identifies it as a first-year-flowering selection, so seed-grown plants can contribute in their first season under suitable growing conditions. ## Growing conditions Choose full sun and soil that drains freely. The [RHS profile for Dianthus barbatus](https://www.rhs.org.uk/plants/105495/dianthus-barbatus/details) recommends well-drained, neutral to slightly acidic soil and lists loam and sand. The breeder reports perennial performance in USDA zones 6a–9b; flowering can begin in early spring and return in spring and autumn. ## Maintenance Remove spent flower heads when their display fades; the RHS recommends deadheading as required. Watch for slugs, aphids, rust, powdery mildew, and Fusarium wilt, which the RHS lists as possible Dianthus barbatus problems. Ball Seed classifies this selection as low maintenance and notes slight fragrance, so routine attention can stay light when drainage and sunlight are appropriate.
