Add a bit of drama to your summer garden with 'Northern Exposure Black' coral bells. Though the actual color of the foliage will change based upon the time of year and exposure (sun/shade/part shade?), the medium-sized leaves can be purple, to blue-black, to black, providing a strong backdrop for flamboyantly colored summer flowers. Tall stems of white flowers will bloom from late spring into the fall, attracting bees and hummingbirds, and adding some vertical interest as well.
