Germinating Bird of Paradise Seeds: Scarification Required

Breaking the Hard Seed Coat for Successful Germination

Bird of paradise (Strelitzia reginae) seeds have a tough, impermeable coat that must be scarified before sowing.

Scarification Methods

• Nick with a knife: Make a small incision in the seed coat.
• Sandpaper rub: Lightly rub the seed on fine sandpaper until the coat thins.

Sowing After Scarification

1. Soak scarified seeds in warm water for 24 hours.
2. Sow ½ inch deep in moist, well‑draining mix.
3. Cover pot with clear plastic; keep at 75–80°F (24–27°C).
4. Germination in 4–8 weeks.
