Dianthus are garden classics, appearing in many shapes and colors. Long blooming, perfect for small bouquets-most are fragrant. A cottage garden is not complete without several Dianthus. Dianthus deltoides will be happiest in partial shade, especially in the south. They are at home covering banks, cascading around rocks or over walls, and edging borders. These lush mats flower in June and July.
Benefits from shearing back after first flush of blooms. Foliage is nearly evergreen, so do not cut back for winter. Prefer loose and sandy alkaline soils. Can be divided in spring every 2-3 years.
