When to prune dracunculus canariensis 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 dracunculus canariensis
Snip the dead flower stem at soil level. Remove berry clusters early to prevent self-seeding. Let all leaves senesce completely before cutting stems to the base — the foliage feeds the corm through to dormancy.
Dracunculus canariensis, the Canary Island dragon arum, needs very little pruning. Remove the spent spathe stalk at the base after it collapses. If berries form and you want to limit self-seeding, remove the berry cluster before it ripens. Allow foliage to die back naturally before cutting stems to the ground.

Pruning dracunculus canariensis in the UK — FAQ
When should I prune dracunculus canariensis in the UK?
Prune dracunculus canariensis in early to mid spring.

There is no nesting-bird restriction that realistically applies to dracunculus canariensis, since birds do not nest in it. The Wildlife and Countryside Act 1981 still protects any active nest you do find anywhere in the garden — the rule is about the nest, not the plant.

Once per season. Dracunculus canariensis, the Canary Island dragon arum, needs very little pruning. Remove the spent spathe stalk at the base after it collapses.

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.
