The genus name Thymus is believed to derive from the ancient Greek word thymos, which is associated with the concepts of strength, courage and vitality. The species name citriodorus means “lemon-scented,” referring to the characteristic fragrance of the plant’s leaves, which strongly resembles that of citrus fruits.

Lemon thyme is a perennial aromatic plant belonging to the family Lamiaceae. It is widely cultivated throughout the Mediterranean region as well as in many temperate parts of the world. In Greece, it is found mainly as a cultivated plant in gardens, rock gardens and flowerpots, where it is highly valued for its pleasant fragrance, abundant flowering and hardiness.

The plant has a low, compact growth habit, forming dense clumps approximately 15–30 cm tall and up to 50 cm wide. Its stems are slender and highly branched. The leaves are small, oval, opposite and evergreen, with green or yellowish green coloration depending on the variety. When crushed, they release a strong lemon fragrance, which distinguishes the plant from other thyme species.

The flowers appear from late spring to mid-summer. They are small, pink to lilac in color, and are borne in dense inflorescences at the tips of the stems. The flowering period attracts bees and other pollinating insects, making lemon thyme a valuable melliferous plant.

Lemon thyme is well adapted to Mediterranean conditions and exhibits high drought tolerance. It grows best in sunny locations and in light, well-drained soil. Excessive moisture may cause problems in the root system, while good air circulation helps maintain the plant’s health. It is also relatively cold-hardy and can tolerate low temperatures without significant damage.

Propagation is carried out mainly through cuttings and division of established plants, as these methods preserve the plant’s aromatic characteristics. Lemon thyme generally shows good resistance to pests and diseases, provided that excessively humid conditions are avoided.

Harvesting is usually carried out before or at the beginning of flowering, when the leaves contain the highest concentration of aromatic compounds. The young shoots and leaves are collected and may be used either fresh or dried. The plant is also used to produce an essential oil with a distinctive lemon fragrance.

Lemon thyme is widely used in cooking to flavor meat, fish, salads, sauces and herbal infusions. In addition, it is used in perfumery and in the production of natural cosmetic products.
