Description: Hydrangeas come in a variety of species and cultivars. Most of the 23 species are native to Asia, while 5 species are native to the Unites States. They are deciduous shrubs. The leaves are simple with margins that can be toothed or lobed. Round terminal flowers can be white, pink, blue, or purple depending on the speciman.

The bark, buds, and flowers are toxic if large quantities are ingested. Hygrangeas can get minor pests and diseases such as powdery mildew, leaf spots, aphids, and scale insects.
