Schinus molle, commonly known as Peruvian pepper tree or California pepper tree, is a fast-growing evergreen native to the arid Andean highlands of South America. Seeds display physiological dormancy with a water-impermeable endocarp, but germination is readily improved by acid scarification or soaking in warm water. This drought-tolerant species germinates quickly at warm temperatures with light and moderate moisture, making it relatively easy to propagate from seed.
Before sowing
Use well-draining, light, porous substrate free of pathogens. Sandy potting mix or perlite recommended. Remove pulp from seeds before sowing.
Sowing
What to expect
Tips
Seeds are positively photoblastic and require light for germination. Separate seeds by specific gravity before sowing—heavier seeds that sink have higher viability. Use continuous light at 25°C for best results. Maintain consistent moisture but avoid waterlogging. Dry storage for 3 months or longer before sowing improves germination parameters. Young seedlings grow slowly until established; provide protection and gradual acclimatization before transplanting outdoors. Avoid strong alkaline soils. Fresh seeds germinate better than old seeds.
