clustered bellflower

Product Image
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.

How to care for Campanula glomerata Superba:

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.
