Rosemary is a valuable Old World aromatic shrub from Europe through Asia Minor. It is native to much of the Mediterranean region and most specifically in the south of France. It was classified by Linnaeus into the mint family and he named its genus from the Latin for sea-dew because it is commonly found on the chalk hills along the seacoast. There are only two species grown, and this one was the primary plant used in the herbal pharmacoepia. It remains today a valuable culinary herb and dryland garden plant. This is a very large upright cultivar that dwarfs the original species and makes a fine xeriscape shrub.
Rosmarinus officinalis has been a part of garden lore for centuries. In ancient times rosemary was believed to strengthen memory; in literature and folklore it is an emblem of remembrance and fidelity. In Shakespeare's Hamlet, Ophelia says, "There's Rosemary...that's for remembrance." Rich in aromatic oil, rosemary releases its fragrance when walked upon or crushed. In medieval times, it was thrown on the floor to mask body odor and poor sanitation practices. Medieval gardeners used it to ward away evil spirits. It was also used to season and disguise the taste and smell of gamy meat. Today, Rosemary is used for potpourri, medicinal tea, and as a culinary herb.
