Lavandula lanata, commonly known as woolly lavender, is a Mediterranean shrub native to southern Spain, prized for its silvery-white woolly leaves and dark purple flowers. Seeds germinate moderately well at cool temperatures (15-21°C) with light exposure, typically taking 1-3 months in a greenhouse setting. This species is somewhat easier to germinate than some Mediterranean lavenders but requires careful attention to moisture and drainage.
Before sowing
Cold stratification recommended but not strictly required for warm-climate species; can be omitted in zones 8-10.

What to expect
Tips
Sow seeds on soil surface or press lightly into substrate—do not bury deeply as light is essential for germination. Maintain cool to warm temperatures (15-21°C), not exceeding 25°C. Provide 12-16 hours of daily light. Keep substrate moist but never waterlogged to prevent fungal issues. Optional cold stratification (3 weeks at 4°C) may improve germination rates, particularly beneficial for cooler climates. Seeds prefer well-drained, slightly alkaline soil. Use a heating mat if indoor temperatures are variable. Thin or fast drainage prevents root rot. Seedlings should be transplanted to individual pots once they reach 2-3 inches tall with true leaves developed.
