When to prune hohenbergia stellata 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 hohenbergia stellata
Cut the dead mother rosette at its base with sterilized pruners to free light and space for pups. Remove any dead or rotting leaves from the pups. Separate individual pups when they are a good size, or allow them to form a clump.
Hohenbergia stellata needs minimal pruning. It is monocarpic: after producing its long-lasting red inflorescence the rosette gradually dies while generating basal pups. Once the mother has fully died back, cut it away at the base to give pups more light and space. Otherwise, only remove visibly dead or damaged leaves.

Once per lifecycle for mother removal; otherwise as needed. Hohenbergia stellata needs minimal pruning.

Once the mother has fully died back, cut it away at the base to give pups more light and space. Otherwise, only remove visibly dead or damaged leaves.
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.
