Campanula Glomerata ‘Superba’, Clustered Bellflower, Zones 3-9

Bellflowers are among the most popular of perennials. This selection will produce a low clump of large green leaves. Medium-tall upright stems appear in early summer, bearing large, showy clusters of rich purple funnel-shaped flowers. Terrific for cutting. Plants will quickly form a large clump, so allow plenty of space when planting, or plan to reduce the size each spring. Easily divided in spring or fall. Spreads by rhizomes.  Plants may benefit from a hard clipping back immediately after blooming, to maintain a low, compact mound and encourage re-blooming.
