To grow lavender from seeds, start by cold stratifying them for 2–4 weeks to break dormancy, a step that mimics winter conditions. Sow seeds lightly in a seed mix, keep soil moist (not soggy), and place in a warm spot (65–75°F/18–24°C). Germination takes 2–4 weeks, and once seedlings appear, give them plenty of light. Lavender seeds grow into hardy plants that add beauty to gardens, pots, and even indoor spaces, with blooms that attract pollinators and work well in crafts or cooking.
