About
A clump-forming perennial, up to 1.5m high, with upright stems clad in lance-shaped dark green leaves. Clusters of daisy-like, violet flowers, with fine, narrow petals and golden-yellow central discs, are produced in early autumn.
About the genus
Symphyotrichum includes around 90 species of annuals, biennials and perennials, mostly spread through the Americas, that were formerly included within the genus Aster. Leaves are simple, lance-shaped and entire, but it is their daisy-like flowerheads that they are grown for; central disc florets are typically yellow, surrounded by strap-shaped ray florets in shades of pink, blue, purple or white
