How to Grow and Care for Creeping Thyme (Thymus serpyllum)

Creeping Thyme (Thymus serpyllum) is a charming, low-growing perennial that forms a dense, evergreen mat of fragrant foliage. Native to Europe, western Asia, and northern Africa, it’s prized as a versatile ground cover that bursts into a carpet of tiny, vibrant flowers in summer.

The aromatic leaves release a pleasant herbal scent when brushed or crushed, and the plant thrives in sunny, dry spots where many others struggle.

It’s perfect for filling gaps, suppressing weeds, and adding color and texture without demanding much care.

There are a number of varieties with different growth habit and flower colours, all worthy of consideration in the garden.

How to Grow Creeping Thyme

Creeping Thyme is a sun loving plant, it grows faster and denser in good sun and also requires at least 6 hours of sun a day to flower well. It will grow in part shade, however flowering will not be as prolific and it will not form the dense mat that makes it such a good ground cover.

Once established the growth rate is moderate, if you plant plugs or small plants at around 3 inches apart they should fill in the space in around 18 – 24 months.

Make sure the soil is well drained and humus rich.
Plant in spring for best results.
After planting water in with a liquid seaweed fertiliser.
Mulch around and between plants, this will encourage spreading and help prevent weeds
Use a liquid fertiliser in spring to improve growth rate but do not over fertilise.
In very hot long dry spelld, a deep watering will be beneficial.

Creeping Thyme Care Information

All varieties require a very well drained soil and full sun.

If grown in shade flowering will be restricted and growth will not be a dense as most would like.

Because it it will form a dense mat it can be used as a lawn substitute, however this is not a plant that will take constant foot traffic. Use pavers in areas with regular traffic to lessen the impact.

Wet cold conditions are not suitable, although this is plant that withstand the cold, the combination of wet and cold will cause problems.

Thymus serpyllum will spread by the trailing stems putting down roots, however it is easy to contain and is not an invasive plant.
