'Pinkie Promise' is a low, spreading plant perfect for mass planting along the front of the border. The soft fuchsia pink flowers completely cover the plant in late spring, with sporadic rebloom providing accent color through the rest of the year. Site it in a location with full sun and loose, well-drained soil for the best performance. In trials it has proven to be longer lived compared with other single-flowered pink Dianthus.
Dianthus grow best in loose, well-drained, neutral to slightly alkaline soils. Dianthus can be grown in full sun or part shade, but the foliage will not be as lush and fewer flowers will be produced if it is grown in hot, dry areas. Regular watering during prolonged dry spells will be necessary. However, they are tolerant of short periods of dryness. Plant them at the same level they were growing in the pots, Pinch or snip off dead flowers to prevent seed formation and encourage additional blooming. At the end of the growing season, cut flower stems back to the ground. Mulch is helpful but keep it away from the crown of the plant.
