Cupressus sempervirens, commonly known as Italian cypress or Mediterranean cypress, is an elegant evergreen conifer native to the eastern Mediterranean region and Iran. This species is renowned for its distinctive narrow columnar form and dark green foliage, having been cultivated for centuries as an ornamental tree. Seeds require cold stratification to overcome dormancy and achieve consistent germination, making this a moderately challenging but rewarding species to propagate from seed.
Before sowing
Pre-treatment is required. Dormancy is short but easily broken by cold stratification. Seeds will fail to germinate without this treatment.
Sowing
What to expect
Tips
Maintain consistent moisture during stratification without waterlogging. After stratification, provide warm temperatures (18-25°C), bright light with 6-8 hours daily, and good ventilation to prevent damping off disease. Keep seedlings moist but never soggy. High humidity is beneficial until germination begins. Provide approximately 3mm (1/8 inch) depth of soil/compost cover. Allow 4-6 weeks of cold stratification for more uniform germination. Young seedlings are susceptible to fungal diseases; ensure excellent air circulation.
