Lavandula angustifolia subsp. angustifolia, commonly known as English Lavender or True Lavender, is an aromatic evergreen subshrub native to the western Mediterranean mountains. The species requires cold stratification to break dormancy and exhibit optimal germination rates, typically sprouting within 14-60 days when provided with adequate light and consistent moisture. This is the most commercially important lavender subspecies, valued for its fine-quality essential oil and exceptional fragrance.
Before sowing
Mix seeds with moist vermiculite or peat moss in a sealed plastic bag and refrigerate at 1-5°C (35-41°F) for 4-6 weeks (28-42 days). Check weekly and ensure medium stays damp but not waterlogged. After stratification, allow seeds to reach room temperature before sowing.

What to expect
Tips
Seeds require light to germinate—do not bury them. Press lightly onto soil surface and maintain 12-16 hours of daily grow light exposure. Maintain consistent soil moisture (like a wrung-out sponge) but never waterlogged to prevent fungal damping-off. Use a heating pad to maintain soil temperature at 65-75°F (18-24°C). Open humidity dome briefly daily for air exchange. Once seedlings emerge (2-3 true leaves), reduce humidity by removing or propping open dome. Transplant into larger containers approximately 1 month after germination. Do not fertilize until plants are established in garden soil. Provide excellent drainage in final location with neutral to slightly alkaline soil (pH 6.5-7.5). Lavender dislikes wet feet; overwatering is the primary cause of failure. Gradually acclimate seedlings to direct sunlight before transplanting outdoors in early spring.
