The genus Thymus ( /ˈtməs/ TY-məs; [3] thymes ) contains about 350 [4] species of aromatic perennial herbaceous plants and subshrubs to 40 cm tall in the family Lamiaceae, native to temperate regions in Europe, North Africa and Asia.


Stems tend to be narrow or even wiry; leaves are evergreen in most species, arranged in opposite pairs, oval, entire, and small, 4–20 mm long, and usually aromatic. Thyme flowers are in dense terminal heads with an uneven calyx, with the upper lip three-lobed, and are yellow, white, or purple.

Several members of the genus are cultivated as culinary herbs or ornamentals, when they are also called thyme after its best-known species, Thymus vulgaris or common thyme.

Thymus species are used as food plants by the larvae of some Lepidoptera (butterfly and moth) insect species, including Chionodes distinctella and the Coleophora case-bearers C. lixella, C. niveicostella, C. serpylletorum, and C. struella (the latter three feed exclusively on Thymus).


A considerable amount of confusion has existed in the naming of thymes. Many nurseries use common names rather than binomial names, which can lead to mix-ups. For example golden thyme, lemon thyme, and creeping thyme are all common names for more than one cultivar. Some confusion remains over the naming and taxonomy of some species, and Margaret Easter (who holds the NCCPG National Plant Collection of thymes in the UK) has compiled a list of synonyms for cultivated species and cultivars.

The most common classification is that used by Jalas, in eight sections: [6]

Thymol Chemical compound found in plants including thyme

Thymol (also known as 2-isopropyl-5-methylphenol, IPMP) is a natural monoterpenoid phenol derivative of p-Cymene, C10H14O, isomeric with carvacrol, found in oil of thyme, and extracted from Thymus vulgaris (common thyme), ajwain, and various other plants as a white crystalline substance of a pleasant aromatic odor and strong antiseptic properties. Thymol also provides the distinctive, strong flavor of the culinary herb thyme, also produced from T. vulgaris.

Gatekeeper (butterfly) Species of butterfly

The gatekeeper or hedge brown is most commonly found in southern and eastern Britain and coastal areas of south and south-east Ireland. It is also found in the Channel Islands, but not in Scotland nor the Isle of Man. Given its preference for warmer weather, the restriction of range expansion can be assumed to be due to climate. Colonies vary in size depending on the available habitat, and can range from a few dozen to several thousand butterflies.

Zaatar Levantine herb or herb blend

Za'atar is a culinary herb or family of herbs. It is also the name of a spice mixture that includes the herb along with toasted sesame seeds, dried sumac, often salt, as well as other spices.
