This month I have been exploring several familiar Mediterranean
herbs, which are used in savory holiday cuisine. I’m using J.O. Swahn’s The Lore of Spices for information, and
today I’m learning about the aromatic herb rosemary.
Rosmarinus officinalis
is in the Lamiaceae family (mint
family). Rosemary originated in the Mediterranean and Asia, and has a long
history of uses from symbolic, to medicinal, to culinary. Per Swahn, rosemary
was named by Pliny the historian, to indicate that it grows close to the sea
shore (ros for foam, and mare for the sea spray). During ancient times, rosemary had a religious
role, and was used to strengthen memory and elicit
fertility in the next life.

In Medieval and Renaissance times, rosemary was used as a
medicine, and possibly to cover up the saltiness of preserved meats. In the 17th
century, rosemary was used to flavor pork, lamb, game, and boiled potatoes. We
continue to flavor food with rosemary in modern times; to extract its oils for
use in perfumes, candles, and incense; and to include it as a drought tolerant plant
in the landscape.
Rosemary grows as an evergreen shrub to 2-4 feet (.6-1.2
meters) high. Stems are woody, and mostly square in cross section; young
branches are pubescent, turning to woody with age. Leaves are simple, opposite,
leathery, linear, ½-1 ½ inches long, somewhat rounded at the tip (obtuse),
generally rounded downward to the underside of the leaf (revolute), and woolly
(tomentose) beneath. Flowers grow in tiny clusters (verticillasters) along the
stem, and are pale blue, and rarely pink or white. The calyx grows as a bell (campanulate), with the corolla about three times as long as the calyx to 5/16 inches long. Two-lipped, with the upper lip entire, and the lower lip 2-lobed.
