Laurus is a small genus of evergreen aromatic trees and shrubs in the family Lauraceae, order Laurales. The genus contains three accepted species, the most familiar being Laurus nobilis (bay laurel or sweet bay), prized for millennia as a culinary herb and the source of the classical laurel wreath.
Plants in the genus are slow-growing, large shrubs or trees bearing alternate, ovate leaves that release a characteristic aromatic scent when crushed. They are dioecious, with insignificant yellow male and female flowers carried on separate plants. Though frost-hardy, they perform best in sheltered positions in full sun and may need winter protection in colder temperate climates; container-grown specimens are commonly moved under glass during cold months.
The native range of Laurus spans the Mediterranean basin and the Macaronesian archipelagos — the Azores, Madeira, and the Canary Islands. Fossil evidence shows that laurel forests containing Laurus species were once far more widely distributed around the Mediterranean and across North Africa during warmer, more humid periods before the Pleistocene glaciations. The progressive drying of the Mediterranean basin during successive glaciations forced the genus to retreat to mild refugia in southern Iberia and the Atlantic island chains. Laurus nobilis recovered much of its former Mediterranean range after the last glacial period ended.
Etymology
The genus name Laurus is the classical Latin word for the laurel tree, long associated in ancient Rome and Greece with victory, honour, and poetic achievement — most famously as the material of the laurel wreath (corona laurea) awarded to champions and emperors.
Distribution
Laurus is native to the Mediterranean region and the Macaronesian islands (Azores, Madeira, and the Canary Islands). Laurus nobilis is centred on the Mediterranean; Laurus novocanariensis is confined to Madeira and the Canary Islands. Fossil pollen and leaf records document a formerly broader distribution across the Mediterranean basin and North Africa, contracted by Pleistocene aridity.
History
Fossil evidence shows Laurus species occurring widely around the Mediterranean and North Africa before the Pleistocene glaciations, when the climate was more humid and mild. Successive glaciations dried the Mediterranean basin and restricted the genus to southern Spain, Portugal, and the Macaronesian islands. With the close of the last glacial period, Laurus nobilis re-expanded across much of its former Mediterranean range. The bay laurel has been cultivated and traded in the Mediterranean world since antiquity.
Cultural Uses
Laurus nobilis (bay laurel) has been central to Mediterranean culture for thousands of years. Its dried leaves are one of the foundational herbs of European and Middle Eastern cooking, used to flavour stocks, stews, and marinades. In ancient Greece and Rome the laurel wreath (corona laurea) was the highest symbol of honour — awarded to victorious athletes, poets, and military commanders — an association that survives in modern words such as "laureate" and "baccalaureate".
Cultivation
Plants are slow-growing and frost-hardy but benefit from a sheltered, sunny position in temperate gardens. In areas with prolonged hard frosts, pot-grown specimens are typically overwintered in a cool greenhouse. Laurus nobilis is widely grown as both an ornamental and a culinary herb across the Mediterranean and in temperate regions worldwide; it tolerates clipping well and is commonly trained as standards or topiary.
