Hydrangea - Hamburg, Hydrangea macrophylla 'Hamburg', is a durable and handsome mophead Hydrangea selection with thick, dark green foliage on upright stems. Hamburg's deep blue flowers or mauve tinged blue are on large heads composed of frilly edged wrinkled sepals. It blooms from June until September and grows up to 6 feet in height.
Hamburg grows best in rich, medium moisture, with well-drained soil in part shade. It tolerates full sun only if grown with constant moisture. Soil pH affects flower color (blue color in highly acidic soils and pink color in slightly acidic to alkaline soils). Add aluminum sulfate to soil to make flowers bluer, or add lime to soil to make flowers pinker. Group or mass in a sheltered location of the shrub border. Also a good specimen or accent for protected locations near homes or patio.
