Members of this genus are called Pinks because their serrated petals seem to have been trimmed with pinking shears. These popular perennials have been cultivated for centuries, and their blossoms add a nostalgic flair to any mixed flower bouquet. We enjoy the blooms' sweet clove perfume at the front of the border where they perch above mounds of lovely gray-green foliage. If cut back after flowering, many varieties deliver a second wave of bloom. Dianthus perform best in full sun and well-drained soil.
