Nearly perfect in every way, this hardy plant is pest resistant, heat tolerant and attracts butterflies and other pollinators by the droves. Plus, deer, slugs and rabbits are not a problem for Raven. Beginning in May, expect a proliferation of 1" blooms in an intense shade of purple, white eyes winking merrily out of the masses of flowers. Blooms will continue to appear until the early part of fall. Suitable for Southern gardens.
