Campanula portenschlagiana 'Clockwise' is a vigorous, evergreen perennial known for its cascading habit and masses of vibrant violet-blue, star-shaped flowers. Blooming profusely from late spring to early autumn, this variety is ideal for trailing over walls, filling crevices, or as groundcover in rock gardens and borders. Its low-growing, spreading nature is complemented by lush green foliage, creating a carpet of colour and texture. Thriving in full sun to partial shade and well-drained soil, Campanula 'Clockwise' is easy to maintain and attracts pollinators, adding charm and versatility to any garden.
