Laurus nobilis is an evergreen tree or shrub, broadly conical in habit. It has narrowly oval, leathery, glossy, dark green and extremely aromatic leaves. It bears small, star shaped, pale yellow flowers which are followed on female plants by globose to ovoid, green and then black fruit.

Laurus nobilis also known as the Bay Laurel or Sweet Laurel has a long history of cultivation for many uses. By far the most prolific is culinary, the leaves contain essential oils with a distinct flavour and aroma and once dried will keep at room temperature for up to a year. The whole leaves should not be consumed as they can tear the digestive tract even when cooked and should be removed prior to serving or ground into a paste or powder. In ancient Greece it was used to symbolize high status and was carried into Roman tradition where it symbolized victory. From the Romans it was brought into Christian tradition, where it symbolizes the resurrection of Christ. It is also the source of the words baccalaureate and poet laureate. Plant extracts can be used as diuretics as astringents, the essential oils are also used in massage therapy and aromatherapy.

The etymological root of the binomial name Laurus is the old Latin name of the true Laurel. Nobilis is from the Latin meaning ‘noble’.

Laurus nobilis is very useful to the landscape architect as an ornamental plant that can be shaped into many forms, including a hedge, and when grown as a tree can attain a fine habit. Its stems may be plaited or trained into a spiral and despite its moderately large leaves it can be shaped into complicated forms, pictured is the standard ‘lollipop’ shape popular in garden centres. The plant must be planted in a sheltered location, as it is susceptible to cold and frost damage.

Ecologically, Laurus nobilis does not accommodate a wide variety of biodiversity as the essential oils act as a natural insect repellent.

The Royal Horticultural Society have given Laurus nobilis their prestigious Award of Garden Merit.

Laurus nobilis prefers moist, fertile, well-drained soils. It tolerates most pH of soil.

If maintained as topiary Laurus nobilis should be trimmed with secateurs during summer to encourage a dense habit and to maintain a balanced shape. New shoots should be pruned to a bud facing in the direction of the desired growth. If maintaining as a hedge Laurus nobilis should be trimmed into shape by simply cutting back to a lower leaf or bud in spring or summer.
