A clump-forming herbaceous perennial showcasing narrow, mid-green leaves, and from late summer to mid-autumn, rich violet-purple flowers with distinctive yellow to dark orange centres, attractive to bees and butterflies. Known for its fully hardy nature, this Michaelmas daisy cultivar adds vibrant colour to the autumn garden and large pots. Its 3cm (1.5in) flowers develop a charmingly shaggy appearance as they age, and the cut or dried blooms make a striking addition to floral arrangements. Named after the custodian of the national collection in Worcestershire, Symphyotrichum novae-angliae 'Helen Picton' is celebrated for its exceptional deep purple hue.
