Creeping Bellflower flower

The inflorescence consists of nodding spikelike racemes with numerous drooping flowers. The flowers are bright blue-violet (rarely white), 2 to 4 cm long, with short petioles standing to one side in the axils of the bracts. The bracts are quite different and smaller than the leaves. The sepals are lanceolate to ovate-lanceolate, entire, wide at the base up to 2.5 mm. The corolla is bell-shaped, with five deep lobes slightly ciliate. The flowering period extends from June through September.

 

The flowers are pollinated by insects (bees, flies, butterflies, etc.) (entomophily). The fruit is a capsule with five pores near the base, where the seeds are spread.

This plant has its overwintering buds situated just below the soil surface (hemicryptophyte). It spreads by underground rhizomes and produces deep, taproot-shaped tubers. Both are white and fleshy. Because any piece of the roots can sprout into a new plant, it is extremely hard to eradicate.

Why Is Creeping Bellflower A Problem?

Creeping Bellflower is an alien (non-native) invasive plant, meaning it out-competes crowds-out and displaces beneficial native plants that have been naturally growing in Ireland for centuries.
