Oakleaf Hydrangea Shrub

Oakleaf hydrangea is an upright, multi-stemmed native shrub whose white panicles bloom from mid-spring into early summer, then age through pink or purple to tan. Its broad, dark green oak-shaped leaves turn red, bronze, or purple in autumn, while peeling reddish-brown bark adds winter interest, as documented by [NC State Extension](https://plants.ces.ncsu.edu/plants/hydrangea-quercifolia/) and [UF/IFAS Extension](https://gardeningsolutions.ifas.ufl.edu/plants/ornamentals/oakleaf-hydrangea/). ## Landscape use and size Use oakleaf hydrangea as a specimen or accent, in groups, or as an informal hedge. Mature estimates vary by source: NC State reports up to 8 feet high and 6–8 feet wide, while UF/IFAS gives 6–10 feet high and 3–5 feet wide. Allow room for a substantial shrub and its broad seasonal display. UF/IFAS notes that flowers and seeds attract birds and pollinators. ## Growing conditions UF/IFAS lists USDA zones 5–9. Grow in fertile, organically rich, well-drained soil with medium moisture; full sun to part shade is suitable, with shade useful in hot climates. [The Morton Arboretum](https://mortonarb.org/plant-and-protect/trees-and-plants/oak-leaved-hydrangea/) recommends mulch to keep the roots cool and moist and notes salt-spray tolerance. ## Maintenance Oakleaf hydrangea flowers on old wood, so prune after flowering if shaping is needed. Remove winter-damaged stems after spring growth begins, and water during extended dry spells. The aged panicles may remain after flowering, while exfoliating bark carries texture into winter.
