Rosemary (new name Salvia rosmarinus) is a fragrant, evergreen herbaceous plant native to the Mediterranean region. It is a woody, perennial shrub. The flowers are small, tubular, and usually pale blue or lavender.

Rosemary is widely grown for its aromatic leaves and is valuable for culinary, medicinal, and ornamental purposes.

Rosemary leaves are narrow, needle-shaped, and about 2–4 cm long. They are dark green on top with a silvery-white underside. The leaves are highly aromatic and emit a strong, piney scent when crushed.
