Hydrangea quercifolia (Oakleaf hydrangea) is a species of hydrangea native to the southeastern United States, from North Carolina west to Tennessee, and south to Florida and Louisiana.
It is a deciduous shrub growing to 2.5 m tall with an open crown. The leaves are lobed, somewhat resembling a Red oak leaf in shape, 8–20 cm long and 5–17 cm broad; they differ from oak leaves in being borne in opposite pairs (not alternately), and having a wrinkled surface. The flowers are produced in conical panicles 10–25 cm long; each panicle comprises a large number of small (3–5 mm) creamy-white fertile flowers, and a few larger, pure white sterile bract-like flowers 25–35 mm diameter.
