You're here to buy Poppy seeds online and grow them — not to read a three-paragraph sales pitch about how beautiful poppies are. Fair enough. KVITER carries six varieties across three species: Papaver rhoeas in red, single mix, and Shirley double mix; Papaver nudicaule for cool-season color; and Eschscholzia californica in orange and mixed. All ornamental, all open-pollinated, all perfectly legal to grow anywhere in the US. Poppy flower seeds for sale, no fine print, no surprises in the packet.
Poppy Varieties
Red Poppy — four scarlet petals, near-black center, bristled stems to 90 cm. Short-lived as individual plants but self-seeds so freely it establishes permanently after one sowing. Cut in the morning when buds are just cracking open. It usually blooms in May-June.
Single Mix Poppy. Same species as the red but selected for variation — red, salmon, dusty pink, white, and bicolor forms, some fringed, some picotee-edged. No two plants identical. The one for naturalistic or meadow-style plantings where uniformity isn't the goal. Blooming season lasts from May to July.
Shirley Poppy Double Mix is heirloom strain developed by Rev. William Wilks in the 1880s — no black center, fully colored petals to the base, double and semi-double forms in blush, salmon, coral, lilac, and white. The best rhoeas type for cutting. 50,000 seeds suits meadow-scale sowings or splitting between growers. Blooms in May-July.
Iceland Poppy is the earliest Poppy — blooms in February in zones 7–8, sometimes in December in zone 9–10. Nodding hairy buds straighten as the flower opens. Compact at 30–45 cm, good for containers. Treat as a cool-season annual; it doesn't survive summer heat in most US climates.
Orange California Poppy is low and spreading with feathery blue-green foliage, deep orange flowers with a satin sheen. Closes at night and on cloudy days — normal behavior, not a problem. Thrives in poor, dry soil where rhoeas would fail. Longest season of any variety here.
California Poppy Mix is the same drought tolerance and feathery foliage as the straight orange, but with a palette that extends to cream, yellow, coral, and deep red-orange. Self-seeds into gravel and dry slopes without encouragement. The shifting color mix means different plants peak at different points through the season.
Frequently Asked Questions
Is it legal to grow poppies from seed in the US?
Yes — for all varieties of Poppy seeds for sale. Buying Poppy seeds of these species and growing them is no different from growing cornflowers or cosmos.
The legal complexity that shows up in search results applies specifically to Papaver somniferum — the opium Poppy — which isn't in this catalogue. If you've seen conflicting information online, it's because people conflate the genus. These are different plants.
Do Poppy seeds need cold stratification?
Papaver rhoeas and nudicaule germinate better after a cold-moist period — which is why fall sowing works so well. If you're sowing in spring, a week in the fridge in a damp paper towel before planting helps. California Poppy doesn't need stratification at all; it germinates readily in cool spring soil without any pre-treatment.
Will poppies self-seed and come back next year?
Poppies are annuals, but can self seed if you let them. Skip deadheading on a few plants and they'll scatter hundreds of seeds per head. The result is a colony that gradually shifts around the garden over years. If you want to control placement, deadhead everything before the pods brown and open.
How many seeds do I need per square metre?
For a natural, meadow-style scatter: 0.5–1 gram per square metre. For a denser border: 1.5–2 grams. KVITER offers 2,000-6,000 seed packets, so it’s enough for planting projects. Thin once seedlings reach 5 cm to about 15 cm apart. Crowded poppies stretch toward light and produce fewer flowers per plant.
