Campanula trachelium

Campanula trachelium is a robust, upright perennial producing clusters of rich violet-blue, bell-shaped flowers along tall stems from early to mid-summer. The blooms rise above coarse, toothed foliage reminiscent of nettle leaves, giving the plant its common name.

Naturally suited to cottage gardens and lightly shaded borders, this hardy bellflower brings height and vertical interest to mixed planting. Tough and adaptable, it grows well in both sun and partial shade, and its nectar-rich flowers are particularly attractive to bees. Pairs well with other sun-loving perennials
