How to grow Oriental Poppy

Sunlight
Full sun
Watering
Low; dislikes wet soil, especially in winter
Soil
Well-drained, moderately fertile; deep soil suits the taproot
Soil pH
Neutral to alkaline

Planting

Plant in autumn or spring in full sun with good drainage. Plan for the gap it leaves: the foliage dies away in midsummer and the plant disappears for weeks, so site it behind later perennials such as asters, hardy geraniums or grasses that will fill the space.

Pruning

Cut the whole plant down to the ground once flowering ends and the leaves start to yellow. Water and it will often produce a fresh low rosette of foliage for autumn.

Propagation

Root cuttings in late autumn or winter are the reliable method: lift a plant, cut pencil-thick root sections about 5 cm long, and insert them the right way up in gritty compost. Seed-raised plants vary and named forms will not come true.

Pests and diseases

Downy mildew can grey and distort the foliage in a wet spring. Otherwise few problems, though plants rot in heavy wet ground over winter.

Value to wildlife

The large bowl-shaped flowers produce abundant pollen and bumblebees work them hard for the short season they are open.

Notes

The stems are hollow and heavy in flower and often flop after rain, so support them early with hoops rather than trying to prop them afterwards. Any root fragment left after digging a plant out will regrow.
