When to prune sinningia 'empress' 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 sinningia 'empress'
Pinch off individual spent blooms at their base. When the entire plant yellows and collapses (typically late summer to autumn), cut all stems to just above the soil surface. Store the tuber dry and cool until new growth emerges.
Sinningia 'Empress' (florist's gloxinia) is a tuberous plant that dies back after flowering and enters dormancy — pruning is minimal. Deadhead spent flowers by pinching them off at the base. Once all foliage yellows and collapses after blooming, cut stems back to the soil level and rest the tuber dry until it regrows.

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.
