Poppy (Papaver rhoeas) growing in a UK garden

The common field poppy is one of Britain's most recognisable wildflowers, producing papery scarlet blooms with a black centre from June to August. Native to the UK, it once covered arable fields and became a symbol of remembrance after the First World War. Seeds can lie dormant in soil for decades, germinating whenever the ground is disturbed. Modern Shirley cultivars offer pastel shades of pink, salmon, and white alongside the classic red.

How to grow poppy

Sow seed directly outdoors from March to May, or in September for earlier flowers the following year. Scatter seed thinly on the surface and press in lightly — poppy seed needs light to germinate, so do not cover with soil. Thin seedlings to 15-20 cm apart. Choose a sunny position with poor, well-drained soil. Poppies thrive on neglect and flower best in nutrient-poor ground. Do not feed. Water is rarely needed. Each flower lasts only a day or two, but plants produce buds continuously for weeks. Allow seed heads to ripen and scatter naturally for self-sowing — each capsule contains thousands of tiny seeds. Poppies resent transplanting due to their delicate taproot, so always sow where they are to grow.

Pruning

No pruning needed. Leave attractive seed pods for ornamental value and self-sowing. Clear spent plants in autumn once seeds have dispersed.

Propagation

  • Seed (sow directly March-May or September)
  • Self-seeding (prolific)
