About plant names...

Oakleaf hydrangea is native to North America.

Identification: Oakleaf hydrangea favors calcium-bearing soils and grows in open hardwood forests. Shrubs are up to 8' (2.4 m) tall, and about the same around. Bark is cinnamon-colored and felt-like, peeling when older. Leaves are dark green, opposite, lobed like oak leaves, longer than they are wide, up to 12" (30 cm) long. In the fall, the leaves are attractively colored, including a deep red-violet. Large (up to 12" (30 cm)) flower clusters contain many cream-colored, white or pinkish flowers. Individual flowers are about 1" (2.5 cm) around. Fruits are small brown capsules. See this Hydrangea comparison table.
