Harebell (Campanula rotundifolia) is a rosette-forming, upright perennial that typically grows to 20 inches tall. It is noted for producing attractive, bell-shaped, nodding blue flowers (each to ½ inches long) that bloom singly or in small clusters from the stem tips throughout summer (June-September). This bluebell is native to a variety of different environments including meadows, grasslands, rocky slopes, crevices, alpine areas and sandy shores. From a basal rosette of small, rounded, long-stalked, basal leaves (to 1 inch wide) rise wiry, thread-like stems clad with narrow, alternate, linear leaves (each to 1-3 inches long). Basal leaves usually wither early and disappear before the flowers form. The blooming period occurs from early to late summer, and lasts about 2-3 months. There is no noticeable floral scent. The flowers are replaced by ovoid capsules that contain numerous tiny seeds. These seeds are easily dispersed by gusts of wind. The root system consists of a taproot.

Habitats include sandy Black Oak savannas, hill prairies, crevices of sandstone, limestone, or dolomite cliffs, and shallow rocky soil along streams. It also occurs along roadsides in neighboring states. Generally, Harebell is found in high quality habitats where there are rocky slopes. It also cultivated in gardens.

Easily grown in average, medium moisture, well-drained soils in full sun to part shade. Plants prefer cool summer climates. They appreciate part afternoon shade in hot summer climates. Plants typically need regular and even moisture. Plants are often short-lived, but will easily remain in the garden in optimum growing conditions by self-seeding. Seed may be planted in the garden in late spring for bloom the following year. Plants will spread in the garden by creeping roots. Plants may be propagated by cuttings, but division of mature plants can be difficult.
