When to prune heucherella brass lantern 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 heucherella brass lantern
Snip dead or damaged leaves individually at the base. Cut spent flower scapes down to ground level once blooms are spent.
Heucherella Brass Lantern requires little pruning. In early spring, clear away any foliage that died back over winter. Remove spent flower stalks at the base once blooming ends. Beyond that, leave the plant alone — cutting into healthy growth is unnecessary and can harm the crown.

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.
