Rosmarinus is a genus of perennial plants in the Lamiaceae family, which is native to the Mediterranean region. The most well-known species within this genus is Rosmarinus officinalis, commonly referred to as rosemary. Rosemary is widely used as a culinary herb, in folk medicine, and as an ornamental plant. The genus name Rosmarinus is derived from the Latin words ros, meaning "dew", and marinus, meaning "of the sea", which together translate to "dew of the sea". This name likely refers to the habitat of the rosemary plant, which thrives in coastal areas.

Description

Rosmarinus species are evergreen shrubs that can vary in size. They are characterized by their needle-like leaves, which are often highly aromatic. The flowers of the Rosmarinus plants are small and can be blue, purple, white, or pink. These plants are well adapted to the Mediterranean climate, requiring full sun and well-drained soil. They are drought-tolerant and can survive in poor soils, making them popular in a variety of garden settings.

Taxonomy and Evolution

The taxonomy of Rosmarinus has been subject to review and changes. Recent genetic studies have led to the reclassification of Rosmarinus officinalis into the genus Salvia, with the new name being Salvia rosmarinus. This reclassification is based on molecular phylogenetic evidence, which shows that Rosmarinus is closely related to and nested within Salvia. Despite this taxonomic change, the common name rosemary and the traditional genus name Rosmarinus continue to be widely used.

Conservation

Some species within the Rosmarinus genus are considered at risk due to habitat loss and other environmental pressures. Conservation efforts are important to ensure the survival of these species in their natural habitats.

Cultural Significance
