When to prune gloxinia perennis 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 gloxinia perennis
Cut all stems back to 2–3 cm above soil level as the plant enters dormancy. Allow the rhizome to rest in barely moist soil. Remove any dead leaf debris. Resume watering when new shoots appear in spring.
Gloxinia perennis is a rhizomatous perennial gesneriad that dies back to its rhizome after flowering. Cut stems down to near soil level once foliage yellows and growth ceases for dormancy. Resume normal care when new shoots emerge from the rhizome. No pruning is needed during active growth.

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.
