About
A clump-forming, herbaceous perennial to about 1m with narrow, dark green leaves. Sprays of pink, daisy flowers with yellow centres open from late summer to mid-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
