About
Paeonia officinalis 'Splendens' is a clump-forming, upright perennial peony that flowers in May to June. It grows to about 0.6 m and has deciduous, deeply divided leaves that are often bronze-flushed when young. Plant in full sun to partial shade on deep, fertile loam or clay that is moist but well drained, in a sheltered position and away from deep shade. Avoid early-morning sun on frosted buds to protect developing flowers.

In the garden
A herbaceous perennial from Southern Europe, Paeonia officinalis 'Splendens' sits in the family Paeoniaceae and is grown for its concentrated late-spring display in May–June. The plants form upright clumps to roughly 0.6 m with deciduous, deeply divided foliage that frequently shows a bronze flush when young. Site it in full sun to partial shade on deep, fertile loam or clay with a neutral to slightly alkaline pH; soil should remain moist but be well drained. Give a sheltered exposure and avoid placing it in deep shade; also try to prevent early-morning sun on frosted buds, which can cause bud damage. Hardiness is H6–H7 (very hardy to fully hardy), and the USDA range is 3–8, so it tolerates typical UK winter conditions when not exposed to driving winds or prolonged frost on budding shoots. At about 0.6 m tall, this peony suits the front to mid-height of a perennial border or a sheltered sunny bed where its spring flowers can be seen at close range. After flowering the foliage continues to provide interest, the young leaves often bearing a bronze tint distinct to this selection.

Care notes
Pruning and caring for Paeonia officinalis 'Splendens'
- 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.
