'Freya' Clustered Bellflower is covered with lilac purple star-shaped flowers in May and June. The foliage is green and somewhat pubescent, and flowers for almost 4 weeks. Campanula glomerata 'Freya' is more floriferous than the straight species, with its flower stems comprising about 2/3 of the height of the plant. An introduction from Arie Blom of the Netherlands.
