Perennials

Campanula glomerata

Clustered Bellflower

Campanula glomerata is an herbaceous perennial native to Europe and western Asia, known for its striking clusters of deep violet-blue, bell-shaped flowers and attractive, rich green foliage. Blooming in dense, rounded clusters atop upright stems in late spring to early summer, it creates a stunning display that attracts bees, butterflies, and other pollinators.

Design tip

The long summer show pairs well with plants that peak earlier, keeping one area interesting for months. It takes sun or light shade, which makes it useful along the changing light of a bed edge or a partly shaded border.
