When to prune variegata brunnera 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 variegata brunnera
Snip flower stems at the base once blooms finish. Remove individual damaged leaves cleanly at the petiole. In late autumn, cut all foliage to ground level with clean shears and tidy away the debris.
Brunnera macrophylla 'Variegata' needs very little pruning. Remove spent flower stems after the spring blue blooms fade to keep the plant tidy. Cut away any scorched or tatty leaves in summer. In autumn, cut the whole clump back to the ground after frost. Avoid removing healthy foliage unnecessarily, as it feeds the rhizome.

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.
