Hydrangea macrophylla

Bigleaf Hydrangea, Garden Hydrangea
Hydrangeaceae (Saxifragaceae)
Deciduous, Shrubs

HYDRANGEA

Big, bold leaves and large clusters of long-lasting flowers in white, pink, red, or blue. Summer and fall bloom. Flower clusters may contain sterile flowers (conspicuous, with large, petal-like sepals) or fertile flowers (small, starry petaled); or they may feature a cluster of small fertile flowers surrounded by a ring of big sterile ones (these are called lacecap hydrangeas). Sterile flowers last for a long time (often holding up for months), gradually fading in color.

Hydrangea macrophylla

Shurb is native to Japan. Symmetrical, rounded habit; grows to 4–8 ft. high (or more) and as wide. Thick, shiny, coarsely toothed leaves to 8 in. long; flowers of white, pink, red, or blue (often depending on the soil pH) are held in big clusters.

Garden hydrangeas come with two common flower types: ones with rounded flower clusters are called mophead or hortensia types; while varieties with lacecap flowers have flatter sprays of large sterile flowers surrounding small fertile flowers.

A great performer in areas where winters are fairly mild; disappointing where plants freeze to the ground every year (they may never bloom under these conditions, since the flower buds of most varieties are produced on old wood). Protect in colder zones by mounding soil or leaves over base of plants. Prune after bloom.
