When to prune clematis tangutica in the UK
Why the timing differs here
For shrubs that flower on the current season's growth, the RHS times pruning to early or mid spring — after severe weather has passed and once the growth buds begin to swell. In Britain that is usually March into April rather than the February common in warmer regions; prune too early and the new shoots meet a late frost.
How to prune clematis tangutica
Cut all previous season's stems back to 30–60 cm (12–24 in) above ground level, just above a strong bud pair. This species is vigorous; be bold. Leave silky seedheads for winter interest if desired, then cut.
Yes — Clematis tangutica is a vigorous Group 3 species producing its yellow lantern flowers on new growth in summer and autumn. Hard pruning each late winter prevents a woody, unmanageable plant and maintains a good flowering display. Cut all stems back to 30–60 cm, keeping one or two buds per stem.

Why is UK pruning timing different from American advice?
Most pruning guides online are written for US conditions and anchored to USDA zones. Britain's maritime climate gives milder winters but later, less predictable last frosts — from March in the south-west to mid-May in the north — so the RHS advises against winter pruning for most plants: it pushes out soft growth that a late frost then kills. Britain also has the nesting-bird law, which has no US equivalent.
