Lauraceae Lauraceae, or the laurels, is a plant family that includes the true laurel and its closest relatives. This family comprises about 2850 known species in about 45 genera worldwide (Christenhusz & Byng 2016 ). They are dicotyledons, and occur ma ...
. The genus contains three or more species, including the bay laurel or sweet bay, ''L. nobilis'', widely cultivated as an ornamental plant and a culinary herb.

). They are frost-hardy but in temperate zones they require a sheltered spot in full sun that is not subject to prolonged freezing. Plants in pots can be moved into a cold greenhouse during the winter months.

Fossil history

Fossils dating from before the Pleistocene glaciations show that species of ''Laurus'' were formerly distributed more widely around the Mediterranean and North Africa, when the climate was more humid and mild than at present. It is currently thought that the drying of the Mediterranean basin during the glaciations caused ''Laurus'' to retreat to the mildest climate refuges, including southern Spain, Portugal and the Macaronesian islands. With the end of the last glacial period, ''L. nobilis'' recovered some of its former range around the Mediterranean.
