Oakleaf hydrangeas are native to the Southeastern U.S., and their blooms are white.

Lacecap hydrangeas are characterized by their unique blossom, with open blooms around the perimeter and small bud-like blooms in the center.

The ph of the soil determines the color of the blossoms of many hydrangea plants, but it is not uncommon to see both blue and pink on the same plant.
