Starting Perennial Poppy Seeds in Summer: Indoor vs. Direct Sowing Strategies

Germinating Poppy Seeds in July (Connecticut)

Perennial poppies (Papaver orientale etc.) dislike transplanting. Two options:

Option 1: Start Indoors Now

• Sow a few seeds per individual peat pot.
• Keep moist, warm (70–75°F); germination in 2 weeks.
• Transplant seedlings (pot and all) in late August/early September.

Option 2: Direct Sow in Fall

Broadcast seeds in the desired bed in October. They will overwinter and germinate next spring.

Option 3: Direct Sow in Spring

Sow as soon as soil can be worked in April.

Recommendation: Option 1 gives a head start; Option 2 is easiest and most natural.
