Blackberry Ice’ is a vigorous grower that  forms a full, rounded clump of attractive foliage that stays nice all season long.  The newest leaves are a remarkable iridescent purple with black veining and have amethyst purple undersides.  As the leaves mature, they develop a softly luminescent pewter overlay. Reddish-purple scapes rise above foliage in midsummer carrying clouds of small creamy white flowers. ‘Blackberry Ice’ thrives in sun or shade and will be a garden thriller massed or a container focal point when used in a mixed planter
