Native Yellow-Flowered Perennial for Woodland Shade
Woodland Poppy (Stylophorum diphyllum) is a spring-blooming native perennial for shaded woodland gardens. It produces yellow flowers followed by seed pods and may become dormant during summer after flowering and seed production.
Plants grow best in humus-rich soil with consistent moisture and part shade to shade. They may self-seed where conditions are suitable.
Growing Conditions
- Light: Part shade to shade
- Hardiness Zones: 4–9
- Bloom: Spring
- Soil: Rich in organic matter
- Moisture: Average to moist
Germination Notes
Woodland Poppy seeds are best sown fresh because viability can decline during dry storage. Sow promptly after collection into moist, well-drained growing medium, covering lightly, and protect the seedbed from drying out. Natural seasonal warm and cold periods can help break dormancy; controlled propagation may use a warm-moist period followed by cold-moist stratification. Germination may be delayed until a later spring and varies with seed freshness and storage.
Seed collection year: 2026.
