Laurus nobilis L. |
Laurus nobilis is an aromatic evergreen tree or large shrub with green, glossy leaves, native to the Mediterranean region. It is one of the plants used for bay leaf seasoning in cooking. It is known as bay laurel, sweet bay, bay tree (esp. United Kingdom), true laurel, Grecian laurel,laurel tree or simply laurel. Laurus nobilis figures prominently in classical Greek, Roman, and Biblical culture.
Worldwide, many other kinds of plants in diverse families are also called "bay" or "laurel", generally due to similarity of foliage or aroma to Laurus nobilis, and the full name is used for the California bay laurel (Umbellularia), also in the family Lauraceae.
The laurel can vary greatly in size and height, sometimes reaching 7–18 metres (23–59 ft) tall. Laurus is a genus of evergreen trees belonging to the Laurel family, Lauraceae. The genus includes three species, whose diagnostic key characters often overlap (Mabberley 1997).
The laurel is dioecious (unisexual), with male and female flowers on separate plants. Each flower is pale yellow-green, about 1 cm diameter, and they are borne in pairs beside a leaf. The leaves are 6–12 cm long and 2–4 cm broad, with an entire (untoothed) margin. On some leaves the margin undulates. The fruit is a small, shiny black berry-like drupe about 1 cm long that contains one seed.
A recent study found considerable genetic diversity within L. nobilis, and that L. azorica is not genetically or morphologically distinct.
Laurus nobilis is a widespread relic of the laurel forests that originally covered much of the Mediterranean Basin when the climate of the region was more humid. With the drying of the Mediterranean during the Pliocene era, the laurel forests gradually retreated, and were replaced by the more drought-tolerant sclerophyll plant communities familiar today. Most of the last remaining laurel forests around the Mediterranean are believed to have disappeared approximately ten thousand years ago, although some remnants still persist in the mountains of southern Turkey, northern Syria, southern Spain, north-central Portugal, northern Morocco, Canary Islands and in Madeira.
