When to prune typhonium venosum 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 typhonium venosum
Cut the spent flower spike at the base once it fades. Remove yellowing leaves cleanly at the stem. Allow the plant to die back fully before storing the tuber dry for winter if needed.
Typhonium venosum (voodoo lily) is a tuberous tropical aroid that dies back after flowering and in cool seasons. It needs very little pruning — simply remove the spent spathe/spadix after it fades and cut back yellowing foliage as the plant goes dormant. Wear gloves; the sap is irritating.

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.
