Salvia rosmarinus (/ /), commonly known as rosemary, is a shrub with fragrant, evergreen, needle-like leaves and white, pink, purple, or blue flowers, native to the Mediterranean region. Until 2017, it was known by the scientific name Rosmarinus officinalis (/ /), now a synonym.
It is a member of the sage family Lamiaceae, which includes many other medicinal and culinary herbs. The name "rosemary" derives from Latin ros marinus (lit. 'dew of the sea'). Rosemary has a fibrous root system.
