About
Paeonia lactiflora 'Evening World' is a clump-forming, upright herbaceous perennial peony that flowers in May to June. It reaches about 0.8 m and has deciduous, deeply divided foliage that often shows a bronze flush when young. Plant in full sun to partial shade on deep, fertile loam or clay that is neutral to slightly alkaline and moist but well drained. Give a sheltered position and avoid early morning sun on frosted buds.

In the garden
Paeonia lactiflora 'Evening World' is an herbaceous perennial from central and eastern Asia, carrying the long garden history of P. lactiflora into modern borders. It forms upright clumps to roughly 0.8 m with deeply divided leaves that frequently have a bronze tinge as they emerge. Flowering occurs in May to June. Position it in full sun to partial shade where the soil is deep and fertile — heavy loam or clay suits it provided drainage is good and moisture is retained. Aim for neutral to slightly alkaline soil pH and a sheltered aspect; the plant’s advice to avoid early morning sun on frosted buds helps reduce bud damage in late springs. Its UK hardiness is H6–H7 (very hardy to fully hardy) and it is also rated USDA 3–8, so it tolerates a wide range of garden locations in Britain when given the right soil and shelter. Use the upright clump where a 0.8 m tall perennial fits the composition of the border, keeping it away from deep shade. Note the young foliage’s bronze flush when choosing neighbours so early-season leaf colour complements adjacent spring planting rather than clashes with it.

Care notes
Pruning and caring for Paeonia lactiflora 'Evening World'
- 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.
