Hydrangea seemannii is a rare and exceptional climber, ideal for creating year-round interest on a shady wall. With its glossy, evergreen leaves, it provides constant coverage and a striking backdrop for its long-lasting, lace-cap white flowers. The plant produces large, lance-shaped, evergreen foliage, which serves as a perfect contrast to the rounded clusters of flowers. The flower heads are composed of greenish-white fertile blooms surrounded by delicate white bracts. Flowering typically lasts from June to August, and under mild conditions, it may extend even further. This hardy, self-supporting climber is equipped with aerial roots that enable it to cling to walls, fences, and trellises, requiring minimal maintenance aside from occasional pruning. Hydrangea seemannii is versatile, thriving in a range of conditions from full sun to deep shade, as long as it is planted in a sheltered, well-draining spot.It’s an ideal choice for sheltered courtyards or cottage gardens, where it can be allowed to gracefully climb a wall or cascade over an arbor. Reaching a maximum height of 8–12 meters (26–39 feet) and a spread of 2.5–4 meters (8–13 feet), this climber offers stunning coverage with little effort. Plant height and spread will vary seasonally, and we list plants by pot size rather than a fixed size, so the plant's appearance at the time of delivery may differ from images provided.
