When to prune clematis 'ville de lyon' 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 'ville de lyon'
Cut every stem back hard to a strong pair of buds at approximately 30–45 cm above soil level. Clear away the prunings and mulch the root zone. The plant regrows rapidly and produces its carmine-red flowers from midsummer on new shoots. No mid-season pruning is needed.
Clematis 'Ville de Lyon' is a Group 3 clematis that flowers solely on new season's growth in mid to late summer. Cut all stems back hard to 30–45 cm above ground in late winter each year. Without this annual hard prune the plant becomes bare and woody at the base with flowers only at the tips.

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.
