This collection of five different packets of seed may contain such favourites as Ageratum, Alyssum Saxatile, Alyssum Rosie O’Day, Arabis, Cerastium, Dianthus, Helianthemum or Saponaria. We have selected a combination of colours designed to make a beautiful display in your rockery. Planting directions are inside. STORAGE: If you are not able to plant immediately, please store in a cool, dry place. Heat and moisture severely reduce the germination of the seed.
