Harebell (Campanula rotundifolia), also known as bluebell, is a perennial plant of the bellflower family, generally 15 to 45 cm tall. Its slender, flexible stems bear bell-shaped, violet-blue flowers that bloom from June to July. The basal leaves are rounded or heart-shaped, while those along the stem are narrow and elongated. The flowers, solitary or arranged in small clusters, have five spreading lobes at the tip, giving the corolla a delicate and airy appearance. The fruits are small capsules that release very fine brownish seeds.
This species is widespread in meadows, clearings, rocky outcrops, dunes, roadsides, and pastures. It thrives in poor to moderately fertile soils, dry to slightly moist, provided they are well-drained. Very hardy, it grows best in full sun but also tolerates partial shade. In Quebec, it is most often found in open environments, frequently in dry or rocky sites.
Ecological roles
Harebell is a nectar-bearing plant that attracts many pollinators, including bees, bumblebees, and butterflies. Bumblebees are particularly adept at entering the flowers to reach the nectar. In natural habitats, it contributes to floral diversity and supports certain specialized insects that depend on its summer flowering. Its ability to grow in poor soils also makes it a useful plant for stabilizing slopes and disturbed areas.
Harebell seeds require cold stratification to ensure germination. See the cultivation notes below for more details.
