Who can resist Asters? In the late summer and early autumn they bring much needed colour with their daisy-like flowers. Asters, also called Michaelmas Daises, are also perfect perennial plants for cutting.
Aster Monch has lilac flowers which can appear as early as July. Plant it with Andenken An Alma Potschke which has magenta flowers for a combination to provide flowers well in to autumn. Add in some bright lime green foliage from Euphorbia, Hostas or Ferns to lift the deep green leaves.
