Campanula rotundifolia 'White Gem'

Campanula rotundifolia 'White Gem' is rarely seen in gardens but deserves to be more widely grown. This variety is a pure white form of the wild Harebell. Loose clusters of dainty, bell-shaped flowers nod from slender stems above a mat of small, rounded leaves. Flowering throughout the summer, this hardy perennial makes a fine addition to rockeries, gravel gardens and alpine troughs. Height: 30cm (12). Spread: 25cm (10).
