Richness and colour for September: Michaelmas daisies (asters – see picture of Aster amellus ‘Sonara’ at Hauser and Wirth, Somerset) never fail to delight the eye and attract a variety of insects. The very word Michaelmas, brings thoughts of woodsmoke and low sunlight, Autumn is upon us. Some of the aster family, of North American origin, are now called Symphyotrichum, should you be looking for them. Asters associate well with Japanese anemones, sedums and persicaria. The Dutch planting designer Piet Oudolf excels in graceful plant designs that look wonderful in late summer and autumn.
