Campanula glomerata Superba

For a shot of pure purple in your summer borders, Campanula glomerata Superba is a choice Prince would be proud of! Better known by its common name, the clustered bellflower, it has dense clusters of deep purple bell-shaped blooms each 3cm wide on upright stems, which are produced from June to August. An absolute classic in the herbaceous border, you'll be hard pressed to choose another plant that complements so many others - have a look at our full range of perennials and judge for yourself.

The flowers stems are carried above rosettes of oval-shaped, mid-green leaves. Always a mark of quality, this clustered bellflower has received the Royal Horticultural Society's Award of Garden Merit.

Great In Your Garden...

Equally happy in full sun or partial shade, Campanula glomerata Superba is ideal for the informal style of a cottage garden. It spreads by means of rhizomes (a rooting underground stem) so if it starts to crowd out its neighbours, divide plants in spring. Pair it with geraniums and delphiniums to flower together. Later-blooming anenomes can take over the show when the campanula's flowers start to fade.

Campanulas are really useful for underplanting large roses and shrubs, as the hide the 'bare ankles' of the bigger plants, which are cetainly not the best part of their display!

If you have problems with alkaline or chalky soil, C. glomerata Superba loves those conditions - grow it alongside Echinacea, Rudbeckia, lavender and herbs like rosemary, bay and fennel.
