Buy Campanula glomerata 'Superba' clustered bellflower: Rich purple flowers in early summer

This perennial dies back to below ground level each year in autumn, then fresh new growth appears again in spring.

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

    Dense heads of large, rich purple, bell-shaped flowers appear from June to August on tall stems that rise above rosettes of oval, mid-green leaves. This beautiful bellflower is perfect for a sunny cottage-style or herbaceous border and is equally happy in partial shade.

  • Garden care: Avoid planting out seedlings until all threat of frost has passed. During the growing season water freely and apply a balanced liquid fertiliser each month. Cut back after flowering, both to prevent self-seeding and to encourage a second flush of flowers.

Notes on Campanula glomerata 'Superba'

"An obvious choice for the cottage wall, though it is quite stately so would enhance a formal flower border equally well"

Lovely colour but not terribly long lasting flowering


Bit tall and lanky but striking purple coloured flowers for a while.




Has impact in a border


I have three of these and they certainly make an impressive addition in the middle of a border where their vivid blue flowers stand out.




Very pretty


I have left this review for a year to see how the plants reacted to the weather. Perfect. I have one in a flower bed and one in a pot on the patio. Although they flower only for a few months in mid summer, it is worth it. A very striking plant. We have had a mild winter in this part of the country but I would imagine if we had a hard cold spell this plant would need mulching (f.bed) or covering (pot). I think that because of its upright stance it looks better in the pot.

A Lovely little plant

My original one didn't survive the winter Quickly replaced 9 months later Great service






I absolutely love this plant, the eye cannot help continually wandering to it as the foliage is a lovely colour but the flowers are absolutely stunning. The first comment from my Mother was "why did you only buy one"! I will definitely be buying more. The flower stems do need caning, however the foliage and flowers are so dense you don't notice the canes at all.

The Chelsea Chop (and other methods of extending the flowering season)

Many gardeners who are happy, even gung-ho, with the secateurs when pruning shrubs and climbers are surprisingly reluctant to take the shears to herbaceous perennials. Maybe this is because it just doesn't seem quite right to be cutting back all that new
