- Description
-
Oakleaf hydrangea is an upright, multi-stemmed, deciduous shrub in the Hydrangeaceae (hydrangea) family. While this family of flowering shrubs is widely distributed in Asia and North America, this particular plant is native to the Southeastern United States, where it prefers moist woods and stream banks. It may grow to 8 feet in height and 6 to 8 feet in width. The species epithet indicates the resemblance of its leaves to that of the oak tree (Quercus).
Oakleaf hydrangea grows best in organically rich, well-drained soils with medium moisture. It does well in full sun to part shade, and mulch in the summer helps to keep the soil moist. The plant does need some sun to bloom, usually from mid spring to early summer. Because blooming occurs on old wood, prune if needed immediately after flowering. Winter damaged stems may be pruned in early spring.
The white blooms are arranged in pyramidal clusters that are very showy. Even when not in bloom, the large dark green leaves provide a striking shape. The plant’s more mature branches have an interesting texture when exfoliated in winter.
Oakleaf hydrangea’s unique features make it highly suitable as a specimen or accent plant in the landscape. Alternatively, in large open spaces it may be massed or arranged as an informal hedge.
Quick ID Hints:
- unique, oak-shaped leaf
- reddish-brown exfoliating bark on adult plants
- panicles of white flowers turning pink, then brown
- imbricate, tomentose, brown buds - terminal largest
Insects, Diseases, and Other Plant Problems: Aphids and spider mites are occasional visitors. Some susceptibility to leaf blight and powdery mildew.
