Wide and distinct umbrella-like leaves form beautiful clumps in a woodland setting. The small white flowers, which persist throughout the season, transform into striking umbels of blue-black berries on cerise stalks.

This hybrid has petite green-and-cream variegated foliage with a hint of pink on the undersides. It produces chartreuse and apple green bicolored bracts on airy stems.

From late spring to early summer, this species bears pendent, green-tipped white flowers along arching stems. These mature into spherical black fruit in autumn, when the foliage turns yellow.

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.
