When to prune viola cornuta 'etain' 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 viola cornuta 'etain'
Shear the whole plant back by half with scissors after flowering. In autumn, cut back any frost-damaged or tired stems to just above the basal rosette.
Viola cornuta 'Etain' is a perennial viola that benefits from cutting back after each main flowering flush. Shear plants back by half after the spring flush to encourage fresh compact growth and a second flush in autumn. Deadhead between cuts. Unlike bedding pansies, this perennial can be cut back hard and will re-sprout reliably.

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.
