An excellent and rarely-seen climber for a shady wall providing all-year interest and cover with its leathery, evergreen foliage plus a long season of lace-cap white flowers. Hydrangea seemannii carries large, lance-shaped evergreen leaves that form a backdrop to domed lace-cap flower heads composed of greenish-white, fertile flowers surrounded by white bracts. It boasts a long flowering period, blooming from June to August and occasionally beyond if the weather is mild.
Hydrangea seemannii is a woody, self-supporting climber equipped with aerial roots that will cling to walls and fences or ramble over trellis and requires minimal maintenance other than occasional trimming. A versatile climber, it copes with everything from full sun to deep shade given a sheltered, free-draining position. A rewarding climber for a sheltered courtyard or cottage garden where it can be allowed to scramble informally up a wall or over an arbour. Maximum height: 8–12m (39ft). Maximum spread: 2.5–4m (13ft).
Plant height and spread is seasonal therefore we list by pot size rather than a defined plant size. The height and spread of the plant delivered will vary depending on the season, meaning arrival images are an indication only.
