Description

Lovely 'Ruby Slippers' hydrangea has white summer flowers that turn pale pink, then deep to rose, and are held upright above the foliage. Flowers may reach 9" in length. The dark green foliage turns mahogany-red in fall. The compact habit and large upright inflorescences make it well-suited to residential gardens. Developed by the US National Arboretum from a cross of 'Snow Queen' and 'Pee Wee'.

Pruning Oakleaf hydrangea blooms on old wood, so it is generally best to avoid any kind of regular pruning or trimming. May be pruned selectively as needed to develop a more striking habit.

Uses Mixed borders; woodland gardens; informal hedges and screens; foundation plantings.

Growing Tips Oakleaf hydrangeas are perhaps the most shade-tolerant hydrangea, though blooming and fall color are best with at least some sun each day. They bloom on old wood and exhibit better bud hardiness than other old wood bloomers. These plants perform far better in the landscape than in the container/nursery environment, so don't be put off by a plant that looks less than enticing in its pot. It will redeem itself rapidly once planted in the ground.
