Hydrangeas have come to be known as the unofficial ushers of summer. They begin to bloom in the early spring months and continue on throughout the summer, depending on type. They are a deciduous shrub that prefers to live in shade and requires a lot of water. Hydrangeas are a good indicator if your other garden plants are getting enough water as they begin to wilt when the soil starts to dry up. Most hydrangeas are native to Asian countries and have a long and symbolic history. In North America, there are five main types of hydrangeas  that are grown.
