Aster

Few perennials extend the season as effectively as Asters. Their abundant, starry flowers - ranging from cool blues to vibrant pinks - add a final burst of energy to borders and containers, supporting pollinators and anchoring the display well into autumn.

Our Aster range features hardy, clump-forming perennials known for reliability and strong garden presence. Aster novi‑belgii varieties deliver abundant colour from late summer, producing clouds of violet-blue, pink or lilac flowers that brighten borders and containers alike. Plants are supplied vigorous and ready to establish, ensuring lasting structure and seasonal display.

Where to plant Asters

Asters grow best in moisture-retentive yet well-drained soil with plenty of sun. Good air flow helps keep foliage clean, particularly in damper climates. They suit mixed borders, wildlife-friendly schemes and larger pots, and will thrive even in heavier ground if grit is incorporated or plants are positioned slightly high to reduce winter wet.

Companion plants for Asters

Their plentiful blooms pair naturally with late-flowering perennials such as Sedum, Rudbeckia, Helenium and Echinacea. Grasses like Calamagrostis or Panicum bring soft movement, while earlier-season plants - such as Nepeta or Salvia - help carry colour through the year.

Growing Asters

Keep soil evenly moist during dry spells to support continuous flowering. Apply a spring mulch to feed plants and retain moisture. Taller forms may need light support in exposed gardens, and pinching in early summer encourages a fuller habit. Divide clumps every few years to maintain vigour and prevent overcrowding.
