Hydrangeas, native to Asia and North America, were first introduced into England from China in 1790 by Sir Joseph Banks and, since then, a number of species have been sent to this country from Japan, including Hydrangea macrophylla. French, or Bigleaf, Hydrangeas (H. macrophylla) are very popular, and have been grown in American gardens since the early 1800s. 'Nikko Blue', a mophead type, was first offered in the United States in 1932.

Bare root planting tips:
- If you can't plant immediately, store your plant in a cool location and keep the roots moist or pot in a container with a nursery potting mix from your local garden center.
- Before planting, let the roots soak for several hours as you prepare the site. You'll want to dig a large enough hole so the root mass can spread out and the plant is at the same soil level as when it was growing in the nursery.
- Once planted, water it in well and wait a month before fertilizing. Mulching will help to maintain moisture and raise soil temperatures for faster growth.
