Starting Japanese Fern-Leaf Peony from Seed in Alaska (Zone 3)

Peony Seed Double Dormancy for Cold Climates

1. Sow ½ inch deep; keep warm (70°F) 3 months. Roots grow; no shoots.
2. Seal pots in plastic bags; no light.
3. Move to fridge (35–40°F) for 3 months.
4. Return to warmth; shoots emerge.

This mimics the natural cycle. In Zone 3, you can also sow outdoors in fall for natural stratification, but the controlled method gives better germination.
