Harebell

Harebell

Campanula rotundifolia

Harebell is a delicate perennial wildflower characterized by its slender stems and nodding, bell-shaped blue or violet flowers. Typically growing to a height of 10-50 cm, it features small, rounded basal leaves (which often wither by flowering time) and narrow, linear stem leaves. This plant thrives in dry, open habitats such as grasslands, heaths, and rocky outcrops. While primarily an outdoor plant, it is grown for its charming flowers and ability to attract pollinators. It is not well-suited for indoor cultivation due to its high light requirements and preference for specific soil conditions.
