Regarded as one of the best blue lacecap hydrangeas, Hydrangea macrophylla 'Zorro' is a vigorous deciduous shrub laden with large flat flowers from early to late summer. Borne on sturdy, deep purple-black stems, the flower heads are composed of huge ultramarine florets, sometimes adorned white centers, radiating around a central cluster of tiny fertile blue flowers. In alkaline soils, the flower heads turn a pleasant bright pink color. The profuse blossoms are beautifully framed by the foliage of glossy, dark green leaves, which colors well in fall. 'Zorro' is an outstanding landscape shrub for lightly shaded gardens or for containers.
