The Oakleaf Hydrangea is one of just a few hydrangeas native to the United States. It gets its name from the shape of the large, beautiful leaves which can turn brilliant shades of red, orange, yellow, and burgundy in the fall when planted in a sunny location that gets a good dose of afternoon shade. However, the Oakleaf does tend to like shady areas better. Some varieties of this shrub can grow up to 26 feet tall with the flowers being almost 12 inches long, while other varieties will only reach two feet in height. The dramatic white-blooming shrub has four seasons of interest. Even though it blooms best in areas where summer is hot, this hydrangea is also a hardy winter plant. It can thrive in dryer areas and needs little attention.
