When to prune echinacea 'white swan' 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 echinacea 'white swan'
Snip spent flower stems back to a healthy side-shoot or leaf during the growing season. Cut all stems to 3–4 inches above the crown in late winter before new leaves appear.
Echinacea 'White Swan' responds well to deadheading for extended bloom, though leaving seedheads in place rewards birds through winter. Cut the whole plant down to a low rosette in late winter or early spring. Avoid cutting back too early in autumn as the crown needs to harden off.

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.
