Best Types of Hydrangeas for Full Sun

While several species of hydrangeas thrive in shade, panicle hydrangeas (Hydrangea paniculata) are the best for growing in full sun. These summer-blooming shrubs produce large clusters of white flowers for several weeks. The showy blooms fade to shades of pink or red before drying to beige. In many areas, the blooms dry on the plant in the fall and continue looking good through most of the winter. Hydrangea paniculata is one of the hardiest species; it thrives in Zones 4-8.

Outstanding Panicle Hydrangea Varieties

  • 'Grandiflora' is sometimes called peegee hydrangea. It's a large shrub or small hydrangea tree up to 20 feet tall.
  • 'Limelight' bears light lime-green flowers from midsummer to fall. It grows eight feet tall.
  • Vanilla Strawberry (Hydrangea paniculata 'Rehny') bears large clusters of white flowers that fade to strawberry pink from midsummer to autumn. It grows about seven feet tall.

Best Types of Hydrangea for Cold-Climates

Smooth hydrangea (Hydrangea arborescens), sometimes called hills of snow or snowball hydrangea, is an especially easy-growing type native to North America. It has clusters of pure white flowers from midsummer into autumn; the older flowers often fade to green before they turn brown and dry.

This extra-hardy type of hydrangea thrives in Zones 3-9 in part shade. While it can take cold temps, it is not very drought tolerant, especially if it's in a spot with afternoon sun. Be sure to water it during dry spells and add a two- to four-inch-deep layer of mulch on the soil around its base to help slow water evaporation.

Popular Smooth Hydrangea Varieties

  • 'Annabelle' bears extra-large clusters of white flowers. It grows five feet tall.
  • 'White Dome' bears fluffy clusters of creamy-white flowers. It grows six feet tall and is hardy in Zones 4-9.

Best Types of Hydrangea for Low-Maintenance

Elegant oakleaf is one of the easiest types of hydrangea to grow. It's also one of the showiest, thanks to its big clusters of white summertime flowers, attractive peeling bark, and textured foliage that turns brilliant shades of purple-red in fall. Oakleaf hydrangea grows about eight feet tall, making it a good choice for providing summertime privacy or as a backdrop in the shade garden.

Like smooth hydrangea, oakleaf is native to North America and prefers a spot in part shade or even full shade. It stands up to dry soil a bit better than most other types but still appreciates extra water during droughts. Oakleaf hydrangea is hardy in Zones 5-9.

Favorite Oakleaf Hydrangea Varieties

  • 'Alice' offers extra-large blooms and more spectacular fall color. It grows 10 feet tall.
  • 'Little Honey' has golden-yellow foliage and clusters of white summertime flowers. It grows four feet tall.
  • 'Snowflake' bears clusters of double white flowers. It grows eight feet tall.

Best Types of Hydrangea for Season-Long Color

It used to be that the beautiful blue- and pink-blooming bigleaf hydrangeas (Hydrangea macrophylla) would bloom once a year, usually in June. But plant breeders have been hard at work, and their efforts are paying off in new types of hydrangea: rebloomers. Series such as Endless Summer and Let's Dance offer big, colorful mophead or lacecap-type blooms every few weeks in summer and fall. Many of these varieties offer beautiful fall foliage, too, and are hardy in Zones 5-9.

Reblooming hydrangeas prefer a spot that gets morning sun and afternoon shade. They aren't very drought tolerant, so will do best in moist but well-drained soil. You'll also need to give them extra water during dry spells. Otherwise, cutting off fading blooms will encourage the plant to continue producing even more flowers.

The soil's acidity level affects the flower color of blue and pink varieties. The more acidic the soil is, the bluer the flowers will be; the less acidic, the pinker the flowers will be. Add soil sulfur or aluminum sulfate for bluer flowers and dolomitic lime for pinker flowers.

Best Types of Hydrangea for Shade

The most unusual member of the clan, climbing hydrangea (Hydrangea petiolaris) is a very slow-growing vine that thrives in full shade in Zones 4-8. It can grow up to 50 feet on a sturdy support. In summer, it bears lacecap-like clusters of white flowers over its rich green foliage.

Select These Standout Varieties

  • 'Firefly' bears green leaves edged in gold and clusters of white flowers.
  • 'Skylands Giant' bears extra large flower clusters.

Regardless of the variety, if eaten, all parts of hydrangeas are toxic to cats, dogs, and other animals, including humans. Supervise pets and small children around hydrangeas in your garden, and keep the cut flowers in your home out of their reach.

How to Fertilize Hydrangeas

Knowing exactly how and when to fertilize hydrangeas, regardless of their type, is the key to success for healthy, long-lasting flowers. When planted right, hydrangeas are really easy to take care of, but it’s the magic of the proper fertilizer that helps them grow and get different hues these beautiful blooms are known for. As a general rule, don’t utilize fertilizer straight away—it’s best to wait at least until the first bloom or the following year and stop doing so after midsummer, preferably in August. Opt for fertilizers with a slow release, which means your flowers will gradually and steadily be fed all the essential nutrients, leading to a healthier, stronger production. It goes without saying, but liquid fertilizers or those labeled as “fast-release” may stunt your hydrangeas’ growth in the long run. In a pinch, homemade compost can also work to nourish and feed your hydrangeas.

Frequently Asked Questions

  • Should you cut your hydrangea bush back?

    In general, hydrangeas do not have to be pruned to bloom beautifully. Unless your bush has grown too large or is infringing on neighboring plants, there is no reason to cut back your hydrangea bushes. That being said, if you do choose to prune your shrubs, you should do so at the end of summer after they've bloomed.

  • How big can hydrangea bushes get?

    Hydrangea bushes come in a range of varietals and a range of sizes. The smallest bushes reach just 2 feet tall and wide at full growth, while the largest hydrangea varietals (most notably, the panicle hydrangea) can grow up to 15 feet tall.

  • When is the best time to plant hydrangeas?

    While the exact timing depends on your growing zone, the best time to plant a hydrangea is generally considered to be early fall, right after the summer heat breaks, which will give the plant plenty of time to establish a strong root system before it blooms.
