Rosmarinus officinalis, a member of the mint family, grown for its highly aromatic leaves and as an ornamental. Rosemary is an evergreen and perennial which can live as long as 20 years under favorable conditions. Although many varieties exist, R. officinalis is the only species. Most varieties are suitable for culinary use, although some (such as Pine Scented) contain high levels of terpenes and have a turpentinelike scent. Other varieties such as Forestii, Collingwood Ingram, and Lockwood de Forest have been developed as ornamentals which have large leaves and showy flowers.
