A perennial deciduous shrub, to small tree. It has 8 to 12-inch-long leaves shaped like oak leaves - hence the name. The flowers are white or pink, and are delicately beautiful. You won't get the large softball sized blooms you would see on the non-native French Hydrangeas, but this native is prolific and stunning in its own right. This shrub holds interest even when not flowering with its stunning foilage. It prefers dry to partially wet soil, but can do well in occasionally wet soil. It can do well in any light conditions, and is a favorite plant to rely on for flowers in shady areas. It will grow to 6 to 10 feet tall and 6 to 8 feet wide. It has little to no salt tolerance. As with many native plants, there are little pests to worry about and once this shrub is established, it will thrive on natural rainfall. If you are looking to brighten up some shady areas in your yard, this beauty is well worth a try.
