Cultivation

Thyme is best cultivated in a hot, sunny location with well-drained soil. It is generally planted in the spring, and thereafter grows as a

perennial In horticulture, the term perennial ('' per-'' + '' -ennial'', "through the year") is used to differentiate a plant from shorter-lived annuals and biennials. It has thus been defined as a plant that lives more than 2 years. The term is also ...

''. Thyme is sold both fresh and dried. While summer-seasonal, fresh greenhouse thyme is often available year-round. The fresh form is more flavourful but also less convenient; storage life is rarely more than a week. However, the fresh form can last many months if carefully frozen, and thyme retains its flavour on drying better than many other herbs. Fresh thyme is commonly sold in bunches of sprigs. A sprig is a single stem snipped from the plant. It is composed of a woody stem with paired leaf or flower clusters ("leaves") spaced apart. A recipe may measure thyme by the bunch (or fraction thereof), or by the sprig, or by the tablespoon or teaspoon. Dried thyme is widely used in Armenia in

s. Depending on how it is used in a dish, the whole sprig may be used, or the leaves removed and the stems discarded. Usually, when a recipe mentions a bunch or sprig, it means the whole form; when it mentions spoons, it means the leaves. It is perfectly acceptable to substitute dried for whole thyme. Leaves may be removed from stems either by scraping with the back of a knife, or by pulling through the fingers or tines of a fork. In Moroccan tradition, dried figs are elevated with the infusion of minty leaves. After softening in a couscous pot, the figs are rested with additional minty leaves before being sprinkled with thyme for a delightful flavor enhancement and preservation in sealed containers.

Phenolic acids such as rosmarinic acid, which is known for its antioxidant, anti-inflammatory, and antimicrobial activities, along with caffeic acid and chlorogenic acid, are also present in thyme. Triterpenes, such as oleanolic acid and ursolic acid, are part of thyme's composition, contributing to its overall health benefits. Additionally, thyme contains tannins, which contribute to its astringent properties, as well as saponins and other minor compounds.
