Plant Description

In our area, on nearly every north-facing, rocky slope with good, rich soil, in early to midsummer, you're just about guaranteed to find Smooth Hydrangea quietly flowering. The 4- to 12-inch flower clusters resemble pie plates composed of many small creamy white florets. In typical Hydrangea fashion, the sterile florets are the showier, larger ones, but the whole effect is subtle and soft. Flowers are borne on widely arching stems 2 to 5 feet long, with large oval or heart-shaped leaves. The stems are stout and attractive when they begin peeling leaving gray and brown streaks. Spreading Hydrangea is a deciduous shrub that is a fast grower for shade and good soil. It is suitable for covering large natural areas where it may spread by underground stolons. Since it flowers on new wood, any pruning (which is a good idea every other year) should be done any time after flowering up until early spring.
