When to prune houttuynia cordata 'chameleon' 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.

Houttuynia cordata 'Chameleon' is vigorous and spreading; cut it back hard in autumn to tidy up and reduce its footprint. In spring, trim unwanted runners at the soil surface to contain spread. The colourful foliage regrows strongly each season. Hard pruning does not harm it — it benefits from firm control.

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.
