  • Position: full sun or partial shade
  • Soil: fertile, moist, well-drained, neutral to alkaline soil
  • Rate of growth: average to fast-growing
  • Flowering period: July to September
  • Hardiness: fully hardy

    Tall, branching stems bearing clusters of soft lilac, open, bell-shaped flowers appear from July to September among toothed, mid-green leaves. This tall bellflower is a cottage-garden classic and is perfect towards the back of a mixed or herbaceous border. It's a happy companion for old roses, self-seeds freely, and the flower colour is retained best in partial shade.
