Erythrina lysistemon, the Common Coral Tree, is a deciduous tree native to southeastern Africa, renowned for its spectacular scarlet flowers that bloom in early spring before leaf emergence. The species has physical seed dormancy that is readily overcome by scarification and warm water soaking, making it easy to propagate from seed. This popular ornamental thrives in warm climates and is valued for its rapid growth, drought tolerance once established, and wildlife benefits.
Before sowing
Combine soaking in warm water for 24 hours with mechanical scarification. Use fungicide treatment optional but recommended to prevent damping off.
Sowing
What to expect
Tips
Sow seeds in spring or summer in warm location (20-25°C). Use fungicide treatment (optional but recommended) to prevent damping-off disease. Seeds should be sown about 1-2 cm deep, not deeper. Keep substrate moist but not waterlogged. Place in warm, shaded spot for germination. Discard seeds that float after soaking as they are often infested with insect larvae. Fresh seeds germinate better than stored seeds.
