Abies pinsapo, commonly known as Spanish fir, is a rare Mediterranean conifer endemic to southern Spain and northern Morocco, now listed as endangered. Seeds have short dormancy that is easily broken by cold stratification, making germination relatively straightforward with proper pre-treatment. Light can advance germination onset in some seed populations, though temperature is the critical controlling factor, with optimal results at 15°C.
Before sowing
Short period of cold stratification is essential to break seed dormancy. Untreated seeds generally fail to germinate adequately.

What to expect
Tips
Soak seeds in room temperature water for 24 hours, then cold stratify in refrigerator at 2-4°C for 4-8 weeks in a sealed plastic bag, keeping seeds moist but not waterlogged. Sow seeds 2-3mm deep in well-draining seed compost and press gently. Keep at room temperature (15-20°C) after cold treatment. Germination begins within 2-4 weeks. Avoid oversowing to prevent damping off disease. Once seedlings emerge, provide bright light and consistent moisture. Young trees grow 12 inches per year and are relatively easy to maintain.
