When to Grow

Sow Swan's Down poppy seeds in early spring, as soon as the soil can be worked, or in the fall for warmer climates. These poppies prefer cooler temperatures for germination and can tolerate light frost. Check your local frost dates for a specific planting time. If you’re not sure how to find your first and last frost dates, consult our blog post 'Our Experts Answer Questions, Share Resources.'

How to Sow and Plant

Surface-sow the seeds just barely covering them, as they need light to germinate. Keep the soil moist until the seedlings emerge, usually within 14-21 days. Thin the seedlings to about 8-10 inches apart to give them enough room to grow.

How to Grow

Swan's Down poppies are low-maintenance and drought-tolerant once established. They need minimal watering, and it's best to let the soil dry out between waterings. Deadheading spent blooms is optional, but leaving them will allow for self-seeding​.

How to Save Seeds

  • Poppies are mostly self-pollinating; however, small flies and honeybees may cross-pollinate closely planted varieties.
  • Often self-sows, but you can also harvest seeds when capsules turn brown and dry completely.
  • Save seed over winter in a cool, dark, dry place.
