Constant Beauty® Yellow - Dianthus caryophyllus

Constant Beauty® Yellow is a compact dianthus selection with double, subtly fragrant flowers and an extended garden display, 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 Yellow within its Constant Beauty series, whose plants continue flowering into warm summer weather. ## Flowers and garden role The Yellow selection supplies a bright yellow accent at the front of a sunny border, along an edging strip, or in a mixed patio container. Its compact dimensions are useful in smaller gardens and path margins, where it can repeat in a low line while leaving taller neighboring flowers visible. [Green Fuse lists Constant Beauty Yellow](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/)
