Campanula 'Brantwood' blooms in June with large, violet-blue bells on tall stems. This bellflower is easy to grow, and it blooms the first year from seed.
In my garden, Campanula 'Brantwood' is a nice companion plant for roses, Digitalis lutea and Dianthus carthusianorum. Also called Great Bellflower or Greater Bellflower. Hardy in zones 3-9.
height 3-4'
