Climbing roses, wisteria, clematis, jasmine, honeysuckle and grape vines are the most common choices. The horizontal slats give plants regular horizontal supports at consistent intervals — easier to train than a smooth post or a wire system. Annual climbers like sweet pea grow quickly for a first-season effect while slower perennials establish.

Partial and increasing over time. An unplanted shade pergola provides minimal shade — the slatted roof filters some direct sun but does not block it. As climbing plants establish and cover the slats, the shade underneath increases naturally. Full planting coverage takes two to four years depending on plant choice and vigour.

The shade pergola is designed specifically for planting rather than a solid or polycarbonate roof. If full overhead cover is the priority, the garden, box or premium models with a roof kit are better suited.

On hard surfaces, bolt-down feet are straightforward and leave the surface intact. On soft ground the posts should be concreted in, particularly once the planting establishes and increases the wind loading on the structure.

The pressure treatment used is safe for garden use and does not leach chemicals harmful to plants or soil. The treatment is a standard timber preservative widely used in structures that sit alongside planting.
