Thyme (Thymus vulgaris) is a hardy perennial herb surviving to -15°C across all UK regions. Over 350 species exist, with common thyme for cooking and creeping thyme for paths and lawn alternatives. Plants need full sun and poor, well-drained soil. They become woody after 3-4 years and should be replaced from cuttings taken in summer. Propagate by semi-ripe cuttings June to August for free plants identical to the parent.
Key takeaways
- Hardy to -15°C — thyme survives all UK winters without protection
- Plant in poor, well-drained soil — rich compost causes leggy, flavourless growth
- Take semi-ripe cuttings from June to August for free replacement plants
- Prune after flowering by one-third but never cut into old bare wood
- Replace plants every 3-4 years when they turn woody and unproductive
- Creeping thyme tolerates light foot traffic and makes a fragrant lawn alternative
