blue hydrangea tree

The blue hydrangea tree is a stunning addition to any New Zealand garden, famous for its lush, globe-shaped clusters of vibrant blue flowers displayed atop attractive woody stems. While the term "blue hydrangea tree" commonly refers to hydrangeas pruned into a tree form, these beloved shrubs naturally lend themselves to both shrub and small tree shapes with the right care and training. Their show-stopping flowers light up shaded and partly sunny spots from late spring well into summer, making them favourites for borders, cottage gardens, and statement container displays. For gardening enthusiasts who appreciate colour as well as structure, few plants can match the blue hydrangea tree’s versatility and allure.

5 from 1 customers

Jacaranda mimosifolia, commonly known as the Blue Jacaranda tree, is a tropical-looking tree that is widely planted because of its beautiful and long-lasting blue flowers. Loose clusters of the deep blue-mauve flowers are borne across the tree through spring and summer. The dark green foliage has a fern-like appearance, and in warm climates, it remains evergreen; otherwise, it is deciduous. It typically grows to 12 m tall and 8 m wide. Jacaranda mimosifolia is commonly used in avenue plantings to provide an unforgettable sight, grown as a specimen, added to a mixed planting, or included in a ‘tropical’ garden.

What Is a Blue Hydrangea Tree?

When gardeners talk about a blue hydrangea tree, they’re often referring to Hydrangea macrophylla varieties pruned and trained as single-stem "standards" or small trees. Although hydrangeas are naturally multi-stemmed shrubs, patient pruning encourages them to grow into beautiful, tree-like shapes perfect for patios, pathways, and feature planting. The standout trait, of course, is their outrageously blue blooms, which dazzle when soil acidity is right. These flowers attract pollinators and create striking focal points outdoors.

Popular Blue Hydrangea Varieties

There's a wide range of hydrangeas especially suited to New Zealand’s climate that can be grown as blue hydrangea trees. Some top choices include:

All of these varieties thrive when provided with rich, well-drained soil and shade from the harshest afternoon sun.

Growing and Caring for Your Blue Hydrangea Tree

To cultivate a brilliant blue hydrangea tree, select a site with morning sun and protection from hot, drying winds. Hydrangeas prefer moist but well-drained soils with a lower pH (more acidic) to encourage blue flowers. Many New Zealand gardeners amend their soil with peat, compost, or a sprinkle of aluminium sulfate to enhance blue tones.

Train your plant to a tree shape by removing lower stems while it’s young, and prune annually just after the flowers fade to maintain a tidy form. Regular deep watering, mulching, and feeding with a hydrangea fertiliser will support lush blooms and healthy foliage throughout the growing season.
