Abrus precatorius is a slender perennial climbing vine native to India and tropical Asia. Known as rosary pea or jequirity bean, it produces distinctive bright red seeds with black tips used in jewelry and prayer beads. The plant has highly toxic seeds containing abrin and requires careful pre-treatment for germination.
Before sowing
Seeds have hard seed coat and primary dormancy; require scarification to break dormancy; without treatment seeds fail to germinate
Sowing
What to expect
Tips
Scarification is essential - untreated seeds show no germination; acid treatment for 120 minutes at 30°C achieves 100% germination in 4 days; hot water soaking overnight until seeds swell is alternative method; germination can occur with or without light; requires consistent moisture during germination phase but avoid waterlogging; prefers sunny location; handle seeds with gloves due to toxicity
