Rosemarinus Officinalis is commonly known as Rosemary. It is a woody perennial, evergreen herb with a good fragrance. It has needle-like leaves and white, pink, purple or blue flowers. Rosemary is a member of the mint family Lamiaceae, which includes many other herbs.
The name “rosemary” derives from Latin “Ros Marinus” which means “dew of the sea”. The plant is also sometimes called anthos.
Rosemary is an aromatic evergreen shrub with leaves similar to hemlock needles. The native of the herb in Asia and the Mediterranean, but is reasonably hardy in cool climates. It can withstand droughts, surviving a severe lack of water for lengthy periods. Forms range from upright to trailing; the upright forms can reach 1.5 m (5 ft) tall, rarely 2 m (6 ft 7 in). The leaves are evergreen, 2–4 cm (0.8–1.6 in) long and 2–5 mm broad, green above, and white below, with dense, short, woolly hair. The plant flowers in spring and summer in temperature climates, but the plants can be in constant bloom in warm climates; flowers are white, pink, purple or deep blue. Rosemary also has a tendency to flower outside its normal flowering season; it has been known to flower as late as early December, and as early as mid-February (in the northern hemisphere). In some parts of the world, it is considered an invasive species.
Upon cultivation, the leaves, twigs, and flowering apices are extracted for use. Rosemary is used as a decorative plant in gardens where it may have pest control effects. The leaves are used to flavor various foods, such as stuffing and roast meat.
