'Scent from Heaven' Dianthus are just that! Stunning selections from Dr. Keith Hammett chosen not only for their heavenly perfume and angelic looks, but also for their repeat flowering over spring and summer into the autumn. Their tightly mounding silver foliage and tidy habit makes them a star in perennial borders, planted en masse in dry gardens and gorgeous in patio pots. These little beauties have proven themselves in climatic extremes in both cold and humid parts of the world. Evergreen.
