Constant Beauty® Crush Watermelon - Dianthus caryophyllus

Constant Beauty® Crush Watermelon is a double-flowered garden selection in Green Fuse’s Dianthus hybrid Constant Beauty® series. Its double bicolor flowers add a varied color note to mixed containers and the front of a sunny border. ## Garden character Green Fuse lists Crush Watermelon in the Constant Beauty® hybrid series and describes the Crush selections as double, bicolored and subtly fragrant, with a uniform habit. The breeder’s culture sheet gives garden dimensions of about 6–10 inches tall and 10–12 inches wide; the series is also described as continuing through summer heat. See the [Green Fuse series page](https://green-fuse.com/new/dianthus-constant-beauty/), [2025–26 catalog](https://green-fuse.com/new/wp-content/uploads/2025/07/GreenFuse-Catalog-2025-26-singles.pdf), and [culture sheet](https://green-fuse.com/new/wp-content/uploads/2026/06/Dianthus-Constant-Beauty%C2%AE.pdf). ## Siting Use a sunny position and moist, gritty, well-drained soil. North Carolina Extension describes carnation culture as favoring full sun and drainage, while Green Fuse describes Constant Beauty® as continuing through summer heat. Site plants where water drains promptly; the breeder’s greenhouse finishing targets are production instructions rather than garden watering rules. ## Maintenance Deadhead fading flowers to prolong the display, keep mulch away from the crown, and watch for rust or crown rot where drainage or air circulation is poor.
