Blue Billow Hydrangea is a compact hardy deciduous shrub with a dense habit of rich green foliage that earns burgundy hues in fall. The lace-cap flowers freely bloom on old wood in summer with an opening color that depends on the PH of the soil- in acidic soils the flowers will be light blue while alkaline flowers will be light pink- before maturing to crimson. Best bloom in partial sun and rich, moist well-drained soils.
