If you're looking to add some color and beauty to your garden or landscape, hydrangeas can be a great choice. These flowering shrubs are known for their large, showy blooms and range of colors, from pink and purple to blue and white. However, not all hydrangeas are well-suited for full sun exposure. In this article, we'll take a look at some of the best hydrangeas for full sun and provide tips for growing them successfully.

The Best Hydrangeas for Full Sun

Here are some of the top hydrangea varieties that can tolerate full sun:

Paniculata Hydrangeas

Paniculata hydrangeas, also known as PeeGee hydrangeas, are one of the hardiest and most sun-tolerant types of hydrangeas. They are commonly grown as large shrubs or small trees, and their cone-shaped flower clusters can grow up to 18 inches long. Some popular varieties include 'Limelight', 'Little Lime', and 'Pink Diamond'.

Smooth Hydrangeas

Smooth hydrangeas, also called Annabelle hydrangeas, are another good option for full sun. They have large, round flower heads that can grow up to 12 inches in diameter and come in shades of white and green. 'Annabelle' is the most well-known variety of smooth hydrangea, but newer cultivars like 'Incrediball' and 'Invincibelle Spirit II' offer improved disease resistance and stronger stems.

Bigleaf Hydrangeas

Bigleaf hydrangeas, or mophead hydrangeas, are a popular choice for their showy, globe-shaped blooms. While they typically prefer partial shade, some varieties can handle more sun than others. Look for cultivars like 'Endless Summer', 'Twist-n-Shout', and 'Let's Dance Blue Jangles' that have been bred for improved sun tolerance.

Tips for Growing Hydrangeas in Full Sun

While these hydrangeas can handle full sun, it's still important to provide them with the right growing conditions to help them thrive. Here are some tips to keep in mind:

Choose the Right Location

When planting hydrangeas in full sun, choose a location that gets at least six hours of direct sunlight per day but also has some protection from the hottest afternoon sun. You may also want to consider planting near a tall tree or structure that can provide some shade during the hottest part of the day.

Provide Adequate Water

Hydrangeas need plenty of water to grow and bloom, especially in full sun. Be sure to water deeply and regularly, aiming for about an inch of water per week. Mulching around the base of the plant can also help retain moisture in the soil.

Fertilize Regularly

To help your hydrangeas stay healthy and vibrant, fertilize them regularly with a balanced fertilizer that's high in phosphorus. This will encourage blooming and strong root growth.

Prune Carefully

While hydrangeas don't require extensive pruning, it's important to remove dead or damaged wood and shape the plant as needed. Avoid pruning too late in the season, as this can remove next year's flower buds.

Protect from Pests and Diseases

Hydrangeas can be susceptible to a range of pests and diseases, including aphids, spider mites, and powdery mildew. Keep an eye out for signs of trouble and treat promptly with insecticidal soap or fungicide if needed.
