Dianthus had a short blooming season until 1971, when a breeder learned how to grow forms that did not set seed and, therefore, had a prolonged their bloom period. Modern varieties will typically bloom from May to October.
The perennial varieties include Cheddar (D. gratianopolitanus), Cottage (D. plumarius) and Grass pinks (D. armeria). The foliage on all of these is blue-gray and each comes in a rainbow of colors.
Some varieties of dianthus are self-sowing, so deadheading is extremely important to reduce volunteer plants and to encourage additional blooming.
The dianthus plant is also called Sweet William (Dianthus barbatus) and has a fragrance with cinnamon or clove notes. The plants are small and usually between 6 and 18 inches (15-46 cm.) tall. Dianthus flowers are most often in pink, salmon, red and white hues. The foliage is slender and sparsely spread on thick stems.
Instructions on how to care for dianthus are very straightforward. Water the plants when dry and apply fertilizer every six to eight weeks. You may also work a slow-release fertilizer into the soil at planting, which will release you from the need to feed the plants.
