Campanula rotundifolia

This stunning Bellflower is much loved for its vibrant, star shaped blooms, they will appear from July until October and boast a popping shade of purple. Easy to care for and happy in dappled shade, be sure to grow your hardy perennial in a rockery, wildlife or cottage gardening scheme. Its thin wiry stems and blue-green foliage contrast wonderfully against its flowers and add some extra texture to those dull corners.
