Papaver orientale
Oriental poppy is a long‑lived herbaceous perennial for cold regions. It produces very large papery blooms in late spring. Plants often go summer dormant after flowering which leaves a temporary gap. Growth is best in full sun with well‑drained soil. Sturdy clumps form from a deep taproot which resents transplanting. The flowers show bold basal blotches and crinkled petals. Performance is strongest in areas with cold winters and cooler summers.

How it differs
- Perennial clumps that return yearly; many poppies on the pillar are annuals
- Blooms earlier in the season then goes summer dormant
- Oversized flowers with frequent dark basal blotches
- Needs cold winters; struggles in hot humid summers
Strengths
- Spectacular early color
- Cold‑hardy where winters are severe
- Low maintenance if soil drains well
- Long‑lived when sited correctly
Care in one minute
- Site: full sun; shelter from strong wind if possible
- Soil: well‑drained, average to fertile; pH slightly acidic to neutral
- Water: regular during establishment; low to moderate after; avoid waterlogging
- Feeding: light spring compost or balanced fertilizer
- Support: stake in windy sites; deadhead to tidy or leave pods for structure
- Overwintering: no special care; ensure winter drainage
Watch‑outs
- Foliage collapses after bloom leaving a gap
- Taproot resents transplanting or division
- Crown can rot in poorly drained soils
