General Description

A charming perennial that tends to grow in nooks and crannies in the garden, the roundleaf bellflower produces delicate, pale lavender-blue flowers in late spring and summer. A clump-forming herbaceous perennial, it is native to most temperate areas across the Northern Hemisphere. In addition to spreading by underground runners (stems), it produces copious amounts of seed and will "pop up" in both annoying and picturesque areas of the landscape.

The foliage of this perennial is a light to medium green. The basal leaf is round to oblong and disappear once flowering starts, leaving the thin, linear leaves of the stems. In late spring and summer, wispy branched, thin stems rise up to carry bell-shaped flowers. These fragrant blooms are pale blue, light lavender or white and will attract bees and butterflies. Seeds will be made judiciously and scattered nearby.

Grow blueflower in full to partial sun in a fertile but well-draining soil. It is pretty haphazadly filling the cracks between stepping stones, dry mortar stone walls or on a rocky hillside. It can be grown in a mixed border as a filler between larger plants or naturalized in a short grass meadow or unmown lawn. Cultivar 'Olympica' is a natural form in Washington state in the United States with toothed leaves and slightly larger flowers.
