The Story
Plant Bio
A compact, rounded, deciduous shrub in the mountain hydrangea group. Features dark green, serrated leaves and sturdy stems. Produces large, mophead-style flower clusters in summer whose color is dependent on soil pH, ranging from blue in acidic soils to pink in alkaline soils. Part of the Tuff Stuff(TM) series, this cultivar is noted for its exceptional hardiness and reliable reblooming habit, flowering on both old and new wood. This ensures a prolific display of flowers from early summer until frost, even after harsh winters.
