Thymus praecox, commonly known as creeping thyme or mother of thyme, is a low-growing, mat-forming aromatic perennial native to Europe. Seeds are photoblastic and require light to germinate; they should be surface-sown or only very lightly pressed into soil without covering. This evergreen groundcover is highly valued for its fragrant foliage and delicate pink to purple flowers that attract pollinators.

What to expect
Tips
Keep seed substrate consistently moist but not waterlogged during germination. Seeds germinate faster at warmer temperatures (18-21°C/64-70°F) and can take 7-30 days. Provide bright light as soon as seeds are sown. Once seedlings emerge, gradually increase airflow to prevent damping off. Thin seedlings to 2-3 per container when large enough to handle. Transplant outdoors after all frost danger has passed. The species establishes quickly and becomes drought-tolerant once mature. No pre-treatment or stratification is required.
