Symphyotrichum dumosum 'Blue Lapis'

A clump forming deciduous herbaceous perennial with stems that reach 50cm (20in) high and as much across. In late summer to autumn, deep blue-violet, semi-double daisies are produced, with a contrasting yellow centre. The flowers are extremely useful late season food source in the wildlife garden for butterlies and other pollinators. Thelate blooming season also makes the plant a useful addition to extend the season of interest in the garden border.
