Oak Leaf Hydrangea: Four-Season Garden Star

The oak leaf hydrangea (Hydrangea quercifolia) delivers summer blooms and spectacular autumn foliage. At maturity, these shrubs reach 4-6 feet high and wide. They tolerate some sun, producing white flowers that age to pink-brown by fall.

The foliage steals the show—turning brilliant purple, orange, and red in September and October. Designated Alabama's state wildflower, these shrubs grace Central Park and major city parks nationwide.

Documented since the 1770s by William Bartram, they thrive in USDA zones 5-9 (roughly Illinois to Houston and St. Augustine). Preferring partial to full sun for best blooms, they're largely trouble-free ornamental shrubs.

Technically deciduous, they're frost-hardy with enormous oak-shaped leaves. Snow-white blooms appear on foot-long stalks in late June, shifting to pink in six weeks. They dry beautifully. Mature stems reveal cinnamon-colored exfoliating bark in winter. Propagation from cuttings is reliable.
