Hydrangea petiolaris (Climbing Hydrangea)

Hydrangea petiolaris is a climbing hydrangea that grows as a vigorous, self-clinging deciduous climber that produces flat white lacecap blooms in early summer. Its heart-shaped leaves create a lush green covering for walls, fences, and pergolas, especially in shaded or semi-shaded areas. Slow to establish but long-lived, this climber thrives in moist, well-drained soil and performs reliably across New Zealand’s diverse climates. Hydrangea petiolaris brings elegance, structure, and seasonal interest to vertical garden spaces.

How to train Hydrangea petiolaris

Training Hydrangea petiolaris, like other climbing hydrangeas, involves guiding its growth and providing proper support. Hydrangea petiolaris can become quite heavy, so choose a sturdy support, such as a strong trellis, a wall, or even a mature tree. They climb by aerial rootlets, which adhere best to rough surfaces such as wood or stone. As the plant grows, gently guide the stems onto the support structure. Use soft ties to loosely secure the stems to the trellis and distribute them evenly across the support structure to create a balanced appearance. Pruning is essential for maintaining shape and controlling growth. It can take some time for Hydrangea petiolaris to cover a wall or trellis, but the wait is worth it!
