About

A clump-forming, deciduous herbaceous perennial with lance-shaped, hairy green leaves and upright stems producing clusters of deep purple-pink daisy-like flowers with yellow centres throughout the 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
