Harebell (Campanula rotundifolia)
This slender and beautiful flower is a perennial growing freely in dry, grassy, well-drained places where the vegetation is short and the soil unimproved. It is native to the United Kingdom and most of Europe. It enjoys both calcareous and acid soils.
The delicate nodding blue flower is unmistakable. It is set on a slender stalk and comprises a bell-shaped corolla with sharp, triangular teeth which is circa 12 – 20 mm long. The buds are erect. The seed is contained in dry capsules. The basal leaves soon wither but the narrow stem leaves persist during flowering. Flowers will be produced from July right until the end of October.
It favours a wide range of habitats including dunes, cliffs, downland and heathland.
