When to prune crocus 'jeanne d'arc' 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 crocus 'jeanne d'arc'
Pinch off or leave the spent flower — either is fine. Do not cut, braid, or remove the grassy leaves until they are entirely yellow and withered.
Crocus 'Jeanne d'Arc' needs virtually no pruning. Once the white flowers fade, remove the spent blooms if desired for tidiness, but the foliage — thin grassy leaves — must be left completely alone until it yellows and dies back naturally, usually 4–6 weeks after flowering, so the corm stores energy for next year.

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.
