Oakleaf hydrangea

What does Oakleaf hydrangea look like?

Oakleaf hydrangea grows as a medium to tall shrub, reaching up to 12 feet. Its leaves are large, deeply lobed, and shaped much like those of an oak tree, with a green upper side and a silvery underside. In autumn, the foliage turns shades of red, bronze, and purple. The plant produces upright, cone-shaped clusters of flowers at the branch tips, which start out creamy white, then shift to pink or brown as they mature. The flowers have a gentle scent, more noticeable than in other hydrangeas.

It is found from North Carolina and Tennessee down through Georgia, Alabama, and into Florida and eastern Texas. The species was first described by botanist William Bartram in the 18th century. Its name comes from the Latin for oak (quercus) and leaf (folium), reflecting the shape of its leaves, though it is not related to true oaks.
