Campanula rotundifolia
''Campanula rotundifolia'' (harebell) is a rhizomatous perennial flowering plant in the bellflower family native to temperate regions of the Northern Hemisphere.
In Scotland, it is often known as the bluebell. Elsewhere in Britain, bluebell refers to ''Hyacinthoides non-scripta'', and in North America, bluebell refers to Virginia bluebell.
==Description==
''Campanula rotundifolia'' is a perennial species of flowering plant, a slender, prostrate to erect herb, spreading by seed and rhizomes. The basal leaves are long-stalked, rounded to heart-shaped, usually slightly toothed, with prominent hydathodes, and often wither early. Leaves on the flowering stems are long and narrow and the upper ones are unstemmed.〔 The inflorescence is a panicle or raceme, with 1 – many flowers borne on very slender pedicels. The flowers usually have five (occasionally 4, 6 or 7) pale to mid violet-blue petals fused together into a bell shape, about long and five long, pointed green sepals behind them. Plants with pale pink or white flowers may also occur.〔 The petal lobes are triangular and curve outwards. The seeds are produced in a capsule about diameter and are released by pores at the base of the capsule. Seedlings are minute, but established plants can compete with tall grass. As with many other ''Campanulas'', all parts of the plant exude white latex when injured or broken.
The flowering period is long, and varies by location. In the British Isles, harebell flowers from July to November.〔 In Missouri, it flowers from May to August; in Minnesota, from June to October.〔(Missouri Plants )〕〔(Montana Plant Life )〕 The flowers are pollinated by bees, but can self-pollinate.
