Constant Beauty® Red - Dianthus caryophyllus

Constant Beauty® Red is a compact dianthus selection valued for a long display of double, subtly fragrant flowers, as described in [Green Fuse's 2025–26 catalog](https://green-fuse.com/new/wp-content/uploads/2025/07/GreenFuse-Catalog-2025-26-singles.pdf). Green Fuse lists Red within its Constant Beauty series, bred to continue flowering in warm summer weather. ## Flowers and garden role The Red selection gives the front of a sunny border or a patio container a clear red accent. Its compact size suits path edging, small-space plantings, and the foreground of mixed perennial beds, where repeated plants can create a continuous low line. [Green Fuse lists Constant Beauty Red](https://green-fuse.com/new/dianthus-constant-beauty/) among the series varieties. ## Size and season Green Fuse gives Constant Beauty a garden height of 6–10 inches and width of 10–12 inches, with USDA hardiness zones 3–10. The culture sheet describes flowering from early spring through summer, continuing late into summer, and notes heat tolerance. [The Constant Beauty culture sheet](https://green-fuse.com/new/wp-content/uploads/2026/06/Dianthus-Constant-Beauty%C2%AE.pdf) provides these series-level garden dimensions and seasonal details. ## Maintenance Choose a sunny site with moist, well-drained soil; North Carolina State's general carnation guidance describes neutral to slightly alkaline soil. Remove spent blooms to encourage continued flowering through summer, as the grower recommends. [North Carolina State Extension](https://plants.ces.ncsu.edu/plants/dianthus-caryophyllus/)
