Harebell, also known as Campanula rotundifolia, is a charming wildflower that grows in temperate regions of the Northern Hemisphere. This perennial plant produces delicate, bell-shaped flowers that range in colour from deep blue to violet, with slender stems that can grow up to 40 cm (16 inches) tall. The flowers are arranged in loose clusters at the top of the stem and typically bloom from midsummer to early autumn.

The basal leaves of the harebell plant are small and round, and often grow in a basal rosette at the base of the stem. They are dark green in colour and have a slightly waxy texture. As the leaves move up the stem, they become very narrow and elongated. The plant's stem is slender, wiry, and slightly hairy, with a reddish tinge that can be seen in some specimens.

Harebell is a hardy plant that prefers to grow in well-drained soil, but can also tolerate clay soils. It is often found growing in rocky or gravelly areas, such as hillsides, upland meadows, and along the edges of forests. The plant is highly adaptable and can thrive in a range of environmental conditions, from full sun to partial shade.

Aside from its ornamental value, harebell is also valued for its medicinal properties. It has been used for centuries as a natural remedy for respiratory ailments such as coughs, asthma, and bronchitis. The plant's leaves and flowers can be dried and steeped to make a tea that is said to have a soothing effect on the lungs.

All parts of the plant exude white latex when injured or broken.

Pollination

By bees, or self-pollination. Self-pollination helps sparse or isolated populations to survive.

Folklore

Harebell, also known as the Scottish bluebell or witches' thimble, has a rich folklore history in many cultures. In European folklore, the plant was believed to have magical properties and was associated with the supernatural. Here are a few examples:

• In Scotland, it was believed that witches would use the flowers of the harebell to summon fairies and other supernatural beings. They would ring the bell-shaped flowers like tiny thimbles to call forth these magical creatures.
• In Norse mythology, the harebell was believed to be sacred to the goddess Freya, who was associated with love, beauty, and fertility. It was believed that wearing a garland of harebells could bring good luck in love and relationships.
• In England, the harebell was believed to be a symbol of bad luck and was associated with death. It was believed that picking the flowers could bring illness or even death, and that they were often found growing near graveyards and other areas associated with death.
• In Welsh mythology, the harebell was associated with the faery queen, Mab, who was believed to ride upon the flowers at night.
• In traditional medicine, the harebell was believed to have healing properties, particularly for respiratory ailments. It was often used as a remedy for coughs, colds, and other respiratory illnesses.

Today, harebell is still considered a symbol of good luck and is often included in gardens for its beauty and ornamental value.
