The oakleaf hydrangea, scientifically known as Hydrangea quercifolia, is a deciduous shrub native to the southeastern United States. It typically grows 4-6 feet tall but can reach up to 8 feet. This shrub is admired for its large, cone-shaped clusters of white flowers that bloom in summer on branches covered with large, oak-like, dark green leaves.



The name "Hydrangea" comes from the Greek words "hydro," meaning "water," and "angeion," meaning "vessel," referring to the cup-shaped fruit of the plant. The specific epithet "quercifolia" is derived from the Latin words for "oak" and "leaf," which describes the shape of the plant's leaves.



One particular cultivar, 'Brenhill,' is smaller than other oakleaf hydrangeas but produces impressively large flowers. The pure white blooms are held upright above the foliage, making it an excellent choice for smaller gardens. These flowers are not affected by soil pH.



Oakleaf hydrangeas thrive in organically rich, well-draining soil with medium moisture and can grow in full sun and shade. They prefer moist soil and benefit from a summer mulch that helps retain soil moisture. Pruning is generally minimal, with pruning needed just after flowering, although any winter-damaged stems can be pruned in early spring. In colder climates like USDA Zone 5, winter protection such as mulching or wrapping in burlap may be necessary, as harsh winters can lead to loss of flower buds or damage to the plant.
