Information about the plant

Lovage is originally found in western Asia but has been cultivated throughout Europe for over a thousand years and, since modern times, also in North America. Wild populations can also be found in these regions. Lovage grows in deep, moist, and nutrient-rich soil and is characterized by a spicy aroma reminiscent of celery when the leaves are rubbed between the fingers. This action damages the tissue and the essential oil with its characteristic smell is released from the oil ducts. The story that an industrialist in the food industry - Julius Maggi (1846-1912) - discovered lovage as a source of a tasty soup seasoning and used it as the basis for his globally marketed 'Maggi' is not true. On the contrary, the Maggi company in Singen forbade some garden centers in Berlin, which distributed lovage to schoolchildren in allotment gardens as the 'Maggi herb' after the First World War, from using this name. �Maggi' was a legally protected trademark registered with the Reichsparteiamt, and the predicative use of the name, which was reserved exclusively for this company, was not permitted. Nevertheless, the name 'Maggi herb' for lovage has survived in the vernacular.

There is widespread speculation about the origin of the name 'lovage', complicated by the fact that the genus name Levisticum was confused with the genus name Ligusticum for a long time. The plant, which is cultivated as a spice and a medicinal plant, is considered to have originated in Liguria (Latin 'ligusticus' = Ligurian), and underwent various name alterations early on, such as transformations in Medieval Latin to 'levisticum', 'livisticum', and 'lubisticum'; the latter may have given rise to the name 'lovage'. The species epithet officinale suggests that it is an old medicinal plant, as the �officina� is the salesroom of a pharmacy, and 'officinale' means commonly used in the pharmacy.

Lovage is a 1 to 2 m high herbaceous perennial with a strong taproot. The two- to three-pinnate leaves sit on a thick, tubular basal axis with upright protruding side shoots. The lower leaflets are up to 70 cm long and 65 cm wide, shiny dark green, and triangular-rhombic in shape. The small, pale-yellow flowers are borne in large 12 to 20-rayed, domed double umbels. The fruits are 5 to 7 mm long, yellow to brown and split into 2 sub-fruits each after breaking off. The flowering time is from July to August.
