What is Evergreen Climbing Hydrangea?

When gardeners in New Zealand talk about evergreen climbing hydrangea, they're usually referring to Hydrangea seemanii. Unlike the more common deciduous varieties, this climbing hydrangea boasts glossy, dark-green leaves all year round and puts on a spectacular summer display of creamy-white flowers. It's ideal for those who love the classic hydrangea look but want the reliability of evergreen foliage, even through the cooler months.

Growing Evergreen Climbing Hydrangea in NZ Conditions

Hydrangea seemanii is well-suited to New Zealand's mild climate, thriving in a sheltered spot with dappled or morning sun. It's a self-clinging climber that attaches itself to walls, trellises, and old trees, making it perfect for softening hardscape and providing privacy. It tolerates coastal conditions and is relatively hassle-free once established, needing just the occasional prune to maintain shape and encourage new growth.

For areas with more shade or a desire for a lush, green wall effect, consider companions like Ficus pumila (Creeping Fig) or Asarina scandens (Climbing Snapdragon) for their contrasting foliage and flowering seasons.

Alternatives to Evergreen Climbing Hydrangea NZ

If you're keen on hydrangeas but want to explore beyond evergreen climbers, there are additional options for New Zealand gardens. Hydrangea petiolaris, the deciduous climbing hydrangea, offers stunning white lacecap flowers and bold, heart-shaped leaves that turn golden in autumn.

For a compact evergreen shrub hydrangea, look at Dichroa Blue Stars (Evergreen Hydrangea). This beauty features metallic blue flowers through summer and evergreen foliage, making it a wonderful choice for smaller spaces or mixed shrub borders.

Where to Plant and How to Care for Evergreen Climbing Hydrangea NZ

Plant evergreen climbing hydrangea in moist, well-drained soil enriched with compost. Position it with morning sun or in filtered light, avoiding harsh midday sun in exposed sites. Mulch around the base to keep roots cool and retain moisture. The hydrangea will slowly climb and cover large areas, rewarding patient gardeners with year-round interest and clusters of delicate flowers in early summer.

Whether you're after the glossy leaves and scented blooms of Hydrangea seemanii or the colour variety of Dichroa Blue Stars (Evergreen Hydrangea), evergreen climbing hydrangea NZ choices are ideal for creating green, vibrant features in gardens across Aotearoa.
