Hydrangea quercifolia Oakleaf Hydrangea

Edward F. Gilman, Ryan W. Klein, and Gail Hansen

Introduction

Oakleaf hydrangea has 8 to 12inchlong leaves shaped like oak leaves. They are borne on stiff, upright, hairy stems which occasionally branch. A fuller shrub can be created by pinching the new growth or cutting back old growth. The plant grows in sun or shade and prefers a rich, moist soil. In the northern part of its range, the top usually dies back during the winter, and it needs shelter from high winds. Oakleaf hydrangea transplants easily and has a very coarse texture and good red fall color. This sprawling, slow-growing shrub reaches 6 to 10 feet tall and spreads three to five feet. The flowers, produced in mid-summer in panicles, are at first white, then fade to pink and then tan. If you wish to prune this hydrangea to create a dense shrub, do so after it flowers so you can enjoy the spectacular flower display.

Use and Management

Because of their size, most residential landscapes only need one or two of these plants. Especially attractive at the edge of woods or other natural settings, oakleaf hydrangea likes fertile, acid, well-drained soil, and requires no attention once it becomes established. It makes a nice accent in a shrub border or growing out of a ground cover.

Available cultivars include 'Snow Queen', large, pure white blooms maturing to pink; 'Snow Flake', large double flowers; and 'Harmony' with 12inchlong, heavy white flower clusters.

Propagation is by seed, cuttings, or separation of the suckers which develop at the base of the plant.

Pest and Diseases

No pests or diseases are of major concern.
