Bigleaf Hydrangea

The mopheads and lacecaps are the workhorses of many summer flower gardens.
Related To:

Plant type: Deciduous shrub
Hardiness: USDA Zones 6 to 9





Bigleaf hydrangeas, a common shrub in the Southeast, are divided into two classes--the mopheads and the lacecaps. There are hundreds of cultivars in each group. Both shrubs flower in the summer, timing dependent on the type and cultivar, and there's considerable variation in flowers. As its name suggests, these hydrangeas have large leaves, giving it a coarse texture in summer. In the winter, the unbranched, vertical stems give the shrub a hopelessly coarse look.

The flower color of some of these hydrangeas depend on the pH of the soil (and, more directly, on how much aluminum is available in the soil). Although there are many exceptions, a pH of 5.0 to 5.5 will result in blue flowers and a pH of above 6 may mean pink flowers.


Bigleaf hydrangeas need moist, well-drained organic soil. Give it full sun to part shade; in the South, shade is essential. Mulch is helpful to help retain soil moisture. Do any pruning immediately after flowering; this shrub flowers on the previous season's growth (there are some exceptions among the cultivars).

'Abracadabra Star'

Abracadabra hydrangeas have silky, jet-black stems which contrast beautifully with the pink blooms in the summer. Since bigleaf hydrangeas like this one have shallow roots, they can benefit from 2 to 3 inches of shredded bark mulch.

'Cityline Venice'

This bigleaf hydrangea variety features pink to blue blooms and grows 2 to 3 feet tall and 3 to 4 feet wide. The color of the blooms depends on the acidity of the soil. The more acidic the soil, the blooms are more likely to be blue. In slightly acidic to alkaline soils, the blooms boast lilac to pink colors.
