Oakleaf Hydrangea Information

Overview

A deciduous, multistemmed, flowering shrub, oakleaf hydrangea is grown for its dramatic cone-shaped flowers and deeply cut foliage. Easy to grow in zones 5 to 9, oakleaf hydrangea forms dense mounds in partial to full shade.

Size

There are several named species of oakleaf hydrangea and they range in size from 3 to 4 feet (Pee Wee) to 6 to 10 feet (Snow Queen).

Color

White flower heads are 6 to 12 inches long. They age to pink and turn rusty-brown in fall.

Sunlight

Oakleaf hydrangea is a southeastern U.S. native, growing in the understory of hardwood forests.

Soil pH

Oakleaf hydrangeas require a soil pH of between 4.5 to 7.0. Unlike mophead hydrangeas, oakleaf flowers do not change color according to soil pH.

Moisture

Hydrangeas can tolerate drought, but might not flower in dry conditions. While oakleaf hydrangea appreciates regular watering, it is prone to rot in wet, boggy soil. Plant in well-drained soil.

Use

In fall, oakleaf hydrangea's foliage turns bronze, gold and purple and persists well into winter. Combined with the rusty-brown flower heads, it adds dramatic winter interest in the garden.
