Ruby Blossom Hydrangea is a compact deciduous shrub with glossy dark green foliage and heavy blooms of fully-double mophead flowers. The dense flower panicle's color depends on the ph of the soil- hot ruby pink in acid soils, purple in neutral, or deep blue in alkane soil- and blooms in summer attracting butterflies. Best bloom in partial sun and rich, moist well-drained soils.
