Rosemary (Rosmarinus officinalis L.) is a woody, perennial herb with fragrant evergreen needle-like leaves that are used in cooking. It is native to the Mediterranean region. It is a member of the mint family Lamiaceae, which also includes many other herbs. Forms range from upright to trailing; the upright forms can reach 1.5 m tall, rarely 2 m. The leaves are evergreen, 2-4 cm long and 2-5 mm broad, green above, and white below with dense short woolly hairs. The flowers are variable in colour, being white, pink, purple, or blue.
The name rosemary has nothing to do with the rose or Mary, but derives from the Latin name rosmarinus, which is presumed to mean "dew of the sea", though some think it too may be derived from an earlier name.
Uses
The fresh and dried leaves are used frequently in traditional Mediterranean cuisine as a herb; a tisane can also be made from them.
Since it is attractive and tolerates some degree of drought, it is also used in landscaping, especially in areas having a Mediterranean climate. It can in fact die in over-watered soil, but is otherwise quite easy to grow for beginner gardeners. It is very pest-resistant.
Numerous cultivars have been selected for garden use. The following are frequently sold:

Rosemary has a very old reputation for improving memory, and has been used as a symbol for remembrance (as in worn during weddings, war commemorations and funerals) in Europe, probably as a result of this reputation; in Shakespeare's Hamlet, Ophelia says, "There's rosemary, that's for remembrance".
Rosemary can be added as an unusual extra flavoring in lemonade.
Rosemary is easily pruned into shapes and has been used for topiary. When grown in pots, it is best kept trimmed to stop it getting too straggly and unsightly, though when grown in a garden, rosemary can grow quite large and still be attractive.
Rosemary is a useful food preservative, according to research published in 1987 by Rutgers University, New Jersey. Researchers at Rutgers patented a chemical derived from rosemary that compares favourably with BHA and BHT in its preservative properties.
