Large group of filler flowers, available in a wide spectrum of colors. Much work has been done in this class of hybrids derived from Aster ericoides, A. nova-belgii, A. nov-angliae and A. amellus, to improve color and delay or eliminate leaf yellowing. Todays modern asters offer variety and excellent vase-life. These filler flowers are part of immense the compositae family, which includes Pompoms, Sunflowers and Dahlias. Nova-Belgii asters feature thin, wiry stems with many sprays of flowers and deep green foliage. The flowers tend to be quite hardy, but can exhibit damage due to poor growing or storage. Check flowers for any damage, as well as the leaves for yellowing. Remove all foliage that will fall below the water-line. Cut stems and place the flowers in a low sugar holding solution. Hold in coolers.
