The Story
Plant Bio
A large, clump-forming perennial prized for its vase-shaped habit and thick, slug-resistant, ovate leaves of a distinct silvery blue-gray. Tall scapes of pale lavender, bell-shaped flowers appear in late summer. Distinguished by its elegant, upright, vase-shaped form, which prevents the leaves from touching the ground. The thick, silvery blue-gray foliage offers excellent slug resistance and holds its color well throughout the season.
