Thymus vulgaris, commonly known as common thyme or garden thyme, is a Mediterranean herb with a long history of culinary and medicinal use. This aromatic evergreen subshrub produces tiny, gray-green leaves with a warm, earthy, peppery flavor. Seed germination is relatively easy but slow and sometimes uneven, typically occurring within 14-28 days under proper conditions with good light and consistent warmth.

Tips
Surface sow seeds as they require light to germinate; do not cover. Maintain consistent moisture but avoid waterlogging. Keep soil warm (18-21°C) in bright light. Germination may be slow and erratic, so be patient. Avoid overwatering seedlings as they are prone to damping off fungal diseases. Thin seedlings gently when several leaves appear. Use fine, lightweight seed compost to prevent smothering tiny seeds. Once established, thyme becomes very drought-tolerant and prefers slightly dry conditions. After 3-4 years, plants become woody and benefit from rejuvenation through new propagation.
