Cultural Notes:
Smooth hydrangea (Hydrangea arborescens) grows in partial shade in average well-drained garden soil; flowering occurs on new wood, so pruning when dormant, even as much as 1-2 ft. from the ground, will encourage more flowers; it will tend to sucker over time and form a colony, so plant it where this will not be a problem.
The flowers show up particularly well in the shady areas that this plant needs.
