Description

(Papaver rhoeas). Shirley/Flanders type. Try not to smile when gazing upon this colorful queen of the garden. This Fleuroselect winner truly reigns supreme. Believed to be the largest of its species, it grows almost 3 times as large as the other Shirley type poppies. Large blooms with picotee edging in magenta to cherry tones with some orange hues always draw attention in beds and borders, especially from butterflies and bees!

Growing Tips: The Supreme poppy is an eye-catching variety that grows best in full sun and moderately rich, well-drained soil. Once established, it's relatively low-maintenance and drought-tolerant, making it a great addition to most gardens.

When to Grow

Sow Supreme poppy seeds in early spring or fall. In colder regions, early spring, as soon as the soil can be worked, is ideal, while fall sowing works well in milder climates. The seeds need cool temperatures for germination and can tolerate light frost​. 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, as they require light to germinate. Scatter them on the soil surface and lightly press them down just barely covering. Keep the soil moist until the seedlings appear, which usually takes 14-21 days. Thin the seedlings to about 8-10 inches apart to give each plant enough room for growth​.

How to Grow

Supreme poppy thrives in full sun, ideally 60-65 F. Water the plants sparingly, allowing the soil to dry out between waterings to prevent root rot. Deadheading spent blooms will encourage more flowers​.

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.
