Campanula glomerata 'Superba'

clustered bellflower

clustered bellflower

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.
