Which climbing plants suit a pergola?
RHS-backed choices and how to plan support, weight and pruning around the structure.
The RHS recommends vigorous climbers for pergolas, including rambling roses, suitable clematis and summer-flowering honeysuckles. Choose for the site's sun, soil and exposure as well as appearance, then check that the pergola can carry mature growth.
Plant weight is not just the nursery pot. Stems, foliage and retained rain build up over time, while dense growth catches wind. The RHS notes that pergolas need solid construction because they may support considerable foliage and face wind buffeting. Ask the pergola maker whether planting is allowed and where supports may be attached, especially on a louvred or motorised roof.
Provide a separate training system where possible. The RHS advises tying new growth in, filling gaps and pruning overlong or dead shoots. Keep stems away from moving louvres, motors, gutters, post outlets and electrical fittings. Do not wind wire around a coated aluminium beam if it can abrade the finish.
Match pruning to the plant. RHS guidance says plants flowering on the previous season's growth are generally pruned after flowering, while those flowering on current growth are often pruned in late winter or spring. Check the specific plant rather than using one date for every climber.
Leave access for inspection and maintenance. A beautiful canopy should not conceal loose fixings, blocked drains or decaying timber. Renovate or thin growth before it becomes unsafe to reach.
