About

An upright perennial to 90cm tall, with narrow leaves and sprays of double, clear pink flowers to 6cm wide in 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

Care notes

CultivationThrives in fertile, moist but well drained soil in sun or partial shade. Plants will benefit from mulching in autumn, and division every few years to maintain vigour. Will not tolerate waterlogging in winter, and may need support, see staking (perennials). For more advice see aster cultivation
PruningCut back in late autumn
PropagationPropagate by division in spring, replanting only vigorous young shoots
Pest resistanceMay be susceptible to slugs and snails on new growth, and to aphids, leaf and bud eelworms and tarsonemid mite
