The traditional lawn is undergoing a rethink now that droughts are becoming more common as the effects of climate change intensify. On drought-prone, free-draining soil, lawn grass turns brown when under stress. In these conditions a creeping thyme lawn is a beautiful, low-maintenance and nature-friendly alternative to a grass lawn, as long as it suits your garden use. Creeping thyme makes a good lawn replacement in the UK, either alone or combined with other prostrate ground cover plants, although thyme rarely thrives as part of a grass lawn because the grass out-competes plants unless the soil is very low in fertility.
