Allegro Oriental Poppy

Start seeds indoors 6-8 weeks before your last spring frost date. Sow seeds on the soil surface or press them lightly into moist seed-starting mix, as Papaver orientale seeds benefit from light exposure for germination. Maintain temperatures around 65-70°F until seedlings emerge. Transplant seedlings to individual containers once they develop their first true leaves.

Harden off seedlings over 7-10 days before transplanting outdoors after the last frost date when soil has warmed. Space transplants 8 inches apart in a full-sun location. The low mounding habit means plants will fill their spacing relatively quickly, creating a dense display.

Direct sow seeds in fall (for spring germination) or early spring once soil is workable. Sow seeds on or just barely press into the soil surface, as they require light for germination. Thin seedlings to 8-inch spacing once they reach 2-3 inches tall.

Deadhead spent blooms to encourage continued flowering and maintain the neat mounding habit. Once the plant finishes blooming for the season, you can cut back the foliage after it dies back naturally in late summer or fall. In spring, remove any winter-damaged growth before new growth emerges.
