Thyme

About this ingredient

This account describes the particular species named below. The common ingredient name can also refer to other species or varieties; it does not identify every product or recipe ingredient by itself.

Which thyme?

Common thyme is Thymus vulgaris. RHS distinguishes its small shrubby habit from creeping thymes. Common names and ornamental cultivars do not establish interchangeable food use.

Growing conditions

RHS lists full sun, well-drained soil, neutral or alkaline pH and UK hardiness H5. Its rating is a regional gardening guide, not a measured survival threshold for every cultivar. The Paris museum recommends sunny, dry calcareous conditions, improved drainage for winter, and propagation by seed, layering or cuttings. Its June–August flowering period describes that garden.

Culinary and regional use

RHS names common thyme in bouquet garni and herbes de Provence. Campania records dried leaves and flower clusters of a local T. vulgaris variety for soups, roasts and tisanes. It assigns cheese dressing to a different creeping thyme; that use is not transferred to common thyme here.

Harvest and drying

RHS describes picking evergreen thyme throughout the year, favouring spring and summer growth. Campania describes gathering flowering branches, drying them in shade and storing separated leaves and flowers cool, dry and dark. This is a regional descriptive method, without a measured drying endpoint or storage life.

Research gaps

No species-specific greenhouse production regime or quantitative heat/humidity limit was established.

Cultivar identity, local collection permission and validated dried-herb storage remain open.

Research status

The underlying plant account received a partial source review. Its review scope is described in the original plant article.
