Dianthus are garden classics, appearing in many shapes and colors, most with blue/green or blue frosted quill-like foliage. Long blooming, perfect for small bouquets-most are fragrant. A cottage garden is not complete without several Dianthus. All are heat tolerant and low maintenance beauties. Dianthus gratianopolitanus forms spreading low mats of blue green foliage.
Shear off old flowering stems and the top couple inches of foliage after blooming. Foliage will quickly recover and look nice, even into winter. Prefers loose and sandy alkaline soils. Can be divided in spring every 2-3 years.
