Hydrangea varieties suitable for zones 3-9.


Mature size differs depending on the variety. Some are as small as 3-feet tall and wide, while others can reach 15-feet tall and 12-feet wide.

Sun or shade?

Most hydrangea plants bloom best in part shade, but some will tolerate full shade or full sun. The amount of sun they can handle depends on your location—in areas further north they can take more sun, while further south they prefer just a few hours of morning sunlight.

Bloom time:

Hydrangeas usually bloom in summer, with some blooming earlier in the season and some later (and if you’re lucky, possibly even into fall).

Flower color:

Most bloom in shades of blue, purple or pink, but there are also white, green, and even some red varieties. Many will open one color and then change colors as they age. Additionally, some hydrangea flower colors (mainly on bigleaf or mountain varieties) can be manipulated to be more blue, pink or purple depending on soil composition and soil pH levels. Learn more about how to change the color of hydrangeas.

Types of hydrangeas:

  • Bigleaf or French hydrangea (H. macrophylla)
  • Oakleaf hydrangea (H. quercifolia)
  • Climbing hydrangea (H. petiolaris)
  • Panicle hydrangea (H. paniculata)
  • Smooth hydrangea (H. arborescens)
  • Mountain hydrangea (H. serrata)

Additionally, there is a wide variety of characteristics to choose from: standard-size hydrangea shrubs, smaller dwarf varieties, or taller tree-like forms. You can also choose from four distinct flower shapes: lacecap, panicle, mophead or snowball. There are also types that bloom on old wood, types that bloom on new wood, and types that bloom on both, often referred to as “reblooming” or “remontant” types.

Compare the sizes, light needs and bloom time of the different hydrangea types and determine which ones meet your gardening needs.

When should hydrangea be pruned?

Fall and the end of winter are the two moments of the year for pruning hydrangeas.

In the fall

Remove dead wood and wilted flowers for a start.
At the end of blooming, it is useless to keep wilted flowers but it is still too early to cut the hydrangea shrub back.
Winter may be cold and if your hydrangea is cut back too much, it may be vulnerable to freezing.
So just remove wilted flowers where the stem meets the branch to freshen up your hydrangea a bit.

  • In autumn, it’s still possible to recover some of your trimmings to start hydrangea cuttings.

At the end of winter

Ideally during the two last weeks of February or the two first weeks of March.
This pruning will be more severe than the one performed in fall, and it will help enhance blooming.

‘Vanilla Strawberry’ is an excellent cut-flower. Simply snip off blooms and group several together for stunning hydrangea bouquets. Or, add complementary blooms in purple and yellow as well as foliage for more variety in hydrangea bouquets. The flowers can also be cut and dried as indoor decor, too.

Because of its size, ‘Vanilla Strawberry’ hydrangea is a great back-of-the-border or foundation shrub. While it can stand alone, the pretty white, pink, and red blooms are well-complemented by smaller shrubs or plants in purples, similar shades of pink, or even foliage-focused plants that are lower growing.

So whether you're looking for a new flowering shrub for your garden or a cut flower for your vase, this hydrangea's large cone-shaped blooms will provide a splash of long-lasting color you can enjoy all summer long.
