PollinationNeeds a second, unrelated plant. A lone oakleaf hydrangea sets almost no seed: its flowers are self-incompatible by a HortScience study of 2004, and 3,000 selfed flowers gave five seedlings in an earlier trial. Plant two unrelated plants for seed.
Black walnutNot named on the Morton Arboretum's lists
ToxicityThe bark, flowers and leaves are poisonous to people, dogs, cats and horses.
GroundRich moist slopes, stream banks, rocky ground and the forest understory
Native in7 states

Oakleaf hydrangea is native in 7 states: Alabama, Florida, Georgia, Louisiana, Mississippi, South Carolina and Tennessee. The states are the USDA PLANTS Database's records, with the native range read from Silvics of North America and NatureServe Explorer. The USDA PLANTS Database also records it growing wild beyond that range in North Carolina and the District of Columbia, where it is naturalized, not native.
