Nizza is a newly introduced Hydrangea macrophylla variety with enormous, flattened lacecap flowerheads. The outer circle of sterile flowers blooms profusely throughout the summer, making for a particularly eye-catching display. Hydrangea macrophylla 'Nizza', like many other kinds, can range from deep pink to bright blue, depending on the pH of the soil. This bushy, well-branched deciduous shrub makes a great choice for a patio pot or mixed border because of its compact, deciduous habit. Height and spread: 120cm (48).
