In order to figure out what type of hydrangea to plant, you'll need to figure out which variety is best for your gardening zone. Start by looking at a planting zone hardiness map to determine the number of your zone. There are hundreds of varieties of hydrangeas to choose from. If this is your first time planting these beautiful flowers, you may want to choose from among these common varieties that are known to be hardy and produce long-lasting blooms.

Annabelle hydrangeas are more cold hardy than mophead or oakleaf hydrangeas, can still grow in zone 3. This type of hydrangea has white blossoms that turn light green later in the season. Peegee hydrangeas can grow hardy even further north than Annabelles - all the way up to zone 3a. They are also able to grow in southern zones. They have white blossoms.

Look for hydrangea plants in your nursery in early spring or early fall. Hydrangeas are easy to grow either in planting beds or in large pots. Whichever method you choose, you'll need a spot that gets full sun in the morning and partial shade in the afternoon. Bigleaf hydrangeas will grow in complete partial shade, so choose this variety if you have a shady yard. Hydrangeas need rich, well-drained soil that is kept moist.
