Genus Campanula (Bellflower)

This campanula is a low-maintenance, hardy perennial that retains its evergreen foliage rosettes through winter. From early summer onward, 'Elizabeth' blooms abundantly against a bright green backdrop of toothed leaves. Slender, upright stems carry elegant, loose racemes of nodding, purple-flushed, pale pink bells that are liberally spotted inside with dark speckles. Individual flowers are 2 to 3 inches long and lightly fragrant.

By late fall, the older crowns die out and young rosettes of leaves appear at the ends of underground rhizomes, giving the illusion that the plants have somehow moved. This casual habit can be annoying in formal beds, but where there is room to naturalize, it is an asset. 'Elizabeth' shines in relaxed plantings under deciduous trees and shrubs, in cottage gardens, in rock gardens, or along pathways leading into the woods.

Serbian bellflowers have an easy, undemanding habit. Creating a stream of lavender blue, the 1-inch-diameter star-shaped blossoms bloom reliably from late spring to early fall. The foliage remains evergreen in mild winters and needs to be sheared only once in a while to keep its appearance tidy. 'Blue Waterfall' flows beautifully along bed edges and through rock gardens in full sun to partial shade.
