Loose clusters of delicate, blue or purple, bell-shaped flowers bloom intermittently atop slender stems from summer through fall.

This attractive flower has a long bloom period. Deadheading spent flowers encourages continuous blooms. Northern Harebell is easily cultivated and does well in a variety of site conditions including dry-to-moist, sandy, well-drained soil. It does best in moist soil, but tolerates dry soil. It grows in full or partial sun; afternoon dappled shade offers some relief in warmer climates. When starting from seed, patience is required, as it does not flower until after the second year. Individual plants are short-lived but they spread through underground rhizomes and self-seed, thereby maitaining their existence in your garden. Naturally occurs in meadows, fields, rocky outcrops, and sandy stream banks. This relatively short statured perennial will be an attractive addition to your native wildflower garden, partly shady woodland edge, or in a cooler location where delicate plantings are required. Best when planted in large groups. Northern Harebell offers some deer resistance. 

Wildlife Value: Native bees and hummingbirds are attracted to the bell-shaped purple flowers.
