About

A compact, spreading deciduous perennial with slim branches of lance-shaped mid green leaves. Large red to pink single daisy-like flowers are produced from summer until 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
