In the garden
Paeonia lactiflora 'Inspector Lavergne' sits in the Paeoniaceae as an herbaceous, clump-forming perennial with an upright habit to roughly 0.8 m. The leaves are deeply divided and frequently show a bronze flush when young, and the bloom season is confined to May to June, providing a clear window of late‑spring flower interest. Give the plant a position in full sun to partial shade on deep, fertile loam or clay with neutral to slightly alkaline pH. Soil should be kept moist but well drained; avoid waterlogged conditions. Choose a sheltered site and avoid deep shade; also protect buds from early morning sun on frosted mornings, which can cause damage. It is rated H6–H7 in the UK (very hardy to fully hardy) and corresponds to USDA zones 3–8. Paeonia lactiflora 'Inspector Lavergne' fits well in mixed herbaceous borders where an upright, seasonally decisive plant is required, or beside structural shrubs that provide winter shelter. Locate it where spring frosts and early-day bright sun do not combine, so emerging buds are not exposed to rapid thaw and freeze cycles that harm flowers.

Care notes
Pruning and caring for Paeonia lactiflora 'Inspector Lavergne'
- Cultivation
- Plant herbaceous peonies with the crown no more than 3cm below the surface — deep planting is the commonest reason a clump never flowers. Enrich the ground thoroughly before planting, then leave undisturbed, and support the heaviest doubles before the buds open.
- Pruning
- Cut herbaceous stems to ground level once the foliage has died back in autumn and clear the debris away, which reduces the risk of peony wilt. Tree peonies need only dead or crossing wood removed after flowering.
- Propagation
- Divide herbaceous crowns in late autumn into sections carrying at least three dormant buds with roots attached, and only once flowering begins to decline. Tree peonies are grafted or layered; seed is slow and variable.
- Pest resistance
- Rarely troubled by pests. Ants on swelling buds are drawn to the nectar and do no harm.
- Disease resistance
- Susceptible to peony wilt in damp seasons; open spacing and prompt removal of affected growth are the best defence.
