Comment:

Hydrangea quercifolia, commonly called oak leaf hydrangea, is an upright, broad-rounded, suckering, multi-stemmed, deciduous shrub that typically grows 4-6' (less frequently to 8') tall. It is native to bluffs, moist woods, ravines and stream banks from Georgia to Florida to Louisiana. 

Specific epithet is in reference to the leaves that look like those of Quercus (oak).

Description:
Deciduous shrubs; leaves opposite, simple, stalked, toothed and sometimes lobed; flowers in terminal, round or umbrella-shaped clusters, white, pink, or blue, 4- 5-parted, the sterile flowers (around the margin or the entire cluster) are much enlarged.
Height:
4-8 ft.
Foliage:
The Oakleaf hydrangea is clad with dark green, large, opposite, simple, bold, leathery 3-7 lobed, oak-like leaves. The leaves which are fuzzy when young are 3-8 inches long. Fall colors are wine, orange, mahogany.
Flower:
The Oakleaf hydrangea is noted for producing pyramidal 4-12" erect panicles of creamy white flowers in summer on exfoliating branches. The fragrant flowers fade to pink, then tan.
Zones:
5-9
Habit:
Deciduous
Site:
The Oakleaf hydrangea is easily grown in organically rich, medium moisture, well-drained soils in full sun to part shade. It thrives in moist soils, and appreciates a summer mulch which helps retain soil moisture. Bloom occurs on old wood. Prune if needed immediately after flowering (little pruning is usually needed). Winter damaged stems may be pruned in early spring. Plants should be given a sheltered location and winter protection (e.g., mulch, burlap wrap) in USDA Zone 5, particularly when not fully established. Plants can lose significant numbers of flower buds or die to the ground in harsh winters (temperatures below -10 degrees F), thus respectively impairing or totally destroying the bloom for the coming year.
