Rosemary (Rosmarinus officinalis) is a drought-tolerant, shrubby member of the Deadnettle Family (Lamiaceae or Labiatae), native to hilly, alkaline slopes overlooking the Mediterranean Sea. In its wild form rosemary grows up to 6 feet tall, bearing spiky leathery leaves and pale blue (occasionally white or pinkish-lilac) two-lipped flowers. Rosemary’s delightful woodsy scent and spicy flavor combine with its rich green needles and exquisite blue flowers to make it a mainstay of any herb garden.
Common rosemary has spawned many cultivars in its journey from the Mediterranean coast to Europe and the New World. All have a shrubby multi-branched appearance, with pine-needle-like leaves — dark green above, silvery on their reverse — and a refreshing, resinous scent and flavor. Some rosemaries grow upright; others creep along the ground (Rosmarinus officinalis var. prostratus). Some bear variegated leaves; gilded rosemary (Rosmarinus officinalis ‘Aureus’), bears leaves tinged with gold. Other cultivars bear blossoms ranging from white to dark blue to lilac-pink to pink and even purplish-red (see “ROSEMARY CULTIVARS” below).
Rosemary grows wild in Spain, where it is called romero or rosmario. It also grows wild in Italy, where it is called rosemarino or ramerino and is one of the commonest culinary herbs, particularly prized with abbachio (roast lamb) and capretto al forno (roast baby goat). Rosemary may also be found growing wild on the island of Majorca; in Sardinia, Greece, and North Africa; and to a limited extent in Turkey, Lebanon and Egypt. Writes Dorothy Bovee Jones, “In southern France, the perfume from the great gnarled woody rosemary plants, clinging to the rocky headlands above the Mediterranean, makes one want to linger and breathe deeply. Sir Francis Bacon [the Tudor writer and explorer] said that when the wind was right, the fragrance from the rosemary reached ships twenty miles at sea.”
ROSEMARY IN HISTORY
Rosemary’s botanic name, Rosmarinus officinalis, betrays an ancient history.
Rosmarinus comes from two Latin words, ros (“dew”) and marinus (“of the sea”), a lovely description of rosemary’s traditional habitat. Officinalis is Latin for “of the pharmacy;” herbs with officinalis in the botanic name were once believed to have medicinal value.
Rosemary was grown by the ancient Egyptians in their wall gardens, and by Arabs in Algeria and Morocco, who bordered their rose gardens with clipped rosemary hedges. The ancient Greeks strewed the floors of their buildings with rosemary, considering it a powerful disinfectant, and burned rosemary as a sacrifice to their gods. Rosemary’s tolerance of salt spray made it valuable in ancient Roman gardens, particularly in spots where salt-intolerant boxwood (Buxus) would not thrive. The Romans wove wreaths of the plant, calling it coronarius (“wreath [plant]“). The Roman poet Ovid mentions rosemary as adorning the hair of the female centaur Hyolonome.
Hatfield reports that Roman and Arab physicians regarded rosemary as particularly effective for restoring speech after a stroke. Rosemary tea was once believed to strengthen the memory, stimulate the appetite, aid the digestion, loosen phlegm in the chest, relieve depression, cure gout, and relieve distress caused by “diseases of the brain.” Burned rosemary wood “was rubbed on teeth to preserve them, and bread baked on it was prescribed to restore the loss of ‘smellynge’.” A box fashioned of aromatic rosemary wood (very old plants can develop quite thick trunks and branches) was thought to preserve one’s youth if it were sniffed regularly. Rosemary, like rue (Ruta graveolens), was also one of the herbs taken into courtrooms for attenders to sniff to protect themselves against “jailhouse fever.” Rosemary wood was also used to fashion musical instruments such as the lute, and to make carpenters’ rulers.
Rosemary was originally brought into England by the Romans. After the Roman legions withdrew from Britain, the herb was taken into monastery gardens. In 814 C.E./A.D. the son of the Emperor Charlemagne (“Charles the Great”), Louis the Pious, had rosemary planted in his royal gardens, probably at Aix-la-Chapelle, Charlemagne’s favorite residence and the site of Louis’s coronation. The Norman French reintroduced rosemary to Britain after 1066. Rosemary was also brought back into Europe from the Middle East by returning Crusaders, and sprigs were carried by medieval pilgrims.
In the second decade of the 14th century, the Countess of Hainault (in what is now France) sent a rosemary plant to her daughter, Philippa, Queen of England. The Countess accompanied her gift with what Jones calls “a poetic treatise on the virtues of rosemary.” In this letter the Countess mentions the medieval French belief that a rosemary bush normally ceased growth when it reached the height of Jesus Christ when he was on Earth, and that when a rosemary bush reached the age of 33 — the age that medieval Christians believed Christ had attained before his death — the bush would never grow any taller, only wider.
The medieval French knew rosemary as l’incensier, the incense herb. Rosemary sprigs and juniper berries were burned in sickrooms and hospitals to disinfect and freshen the air. Rosemary boughs were also burned, and otherwise displayed, in churches. Hatfield reports that medieval people considered rosemary as possessing “mystical powers strong enough to guard the church, the dead and the living from all evil. It was grown in churchyards, and its boughs were kept inside churches.”
One of the longest-held beliefs about rosemary was that it stands for remembrance. “A Handful of Pleasant Delights,” a popular Elizabethan song dated 1566, had a lover croon, “Rosemarie is for remembrance betweene us daie and night;/ Wishing I might always have you present in my sight.” Perhaps for this reason, as much as for its protective virtues, rosemary figured prominently in European weddings. Sprigs were dipped in scented water and woven into the bride’s hair as symbols of marital fidelity; Anne of Cleves wore rosemary branches in her bejeweled gold crown when she married Henry VIII of England. The branches were gilded, tied with colored ribbons, and handed out to wedding guests as symbols of their love and loyalty. For the same reason bouquets of rosemary, tied with ribbons, were handed to bridegrooms by the bridemaids when he first appeared the morning of the wedding.
Rosemary also had its place at funerals. Rosemary sprigs were carried by mourners to the gravesite to be dropped on top of the coffin at the end of the service. This custom is mentioned in Shakepeare’s play, Romeo and Juliet, where he has Friar Laurence say of the dead Juliet, “Dry up your tears and stick your Rosemary/ On this fair corse [corpse].” In regions where it was hardy, rosemary was also frequently planted on graves. Referring to its wedding and funeral uses, Elizabethan poet Herrick — perhaps a trifle depressed at the time — wrote of rosemary, “Grow it for two ends, it matters not at all,/ Be’t for my bridall or my buriall.”
The flowering tops of rosemary branches were soaked in alcohol to create the original Eau de la reine d’Hongrie, the famous medieval Hungary water. 17th century legend has it that Hungary water was invented for Elizabeth, Queen of Hungary, in 1235. She is said to have suffered from paralysis, and legend says that her mobility was completely restored after her limbs were washing in the herb-infused spirits. (See Recipes Section for the formula for Hungary Water.) The French writer Perrault, in his version of the fairy tale “The Sleeping Beauty,” has those attempting to revive the enchanted Beauty apply Hungary water to her temples, but in vain.
Rosemary also figured prominently at Christmas and New Year’s Eve celebrations. It was believed when Mary, Joseph, and the baby Jesus sought shelter on their journey into Egypt to escape King Herod’s slaughter of the innocents. Furtively passing through some bushes, the twigs brushed against the refugees’ clothing, making their presence known to their
pursuers — all but the branches of the rosemary, which drew aside silently to permit the family to pass through undetected. Another legend had it that all rosemary bushes bloomed white until one day the Holy Family stopped to rest beside a rosemary bush. Taking off her — traditionally blue — cloak, Mary flung it over the rosemary bush and the blossoms immediately turned blue. (They have been blue — for the most part — ever since.)
Along with holly and bay leaves, rosemary was one of the evergreens used to “deck the halls” at Christmastime, and rosemary and bay were used to decorate roasted boar’s head, a traditional Christmas Day food. Along with oranges stuck with cloves, rosemary sprigs were given as New Year’s gifts, and wassail bowls were decorated with beribboned rosemary branches.
Rosemary came very early into the New World. It was brought by the Spanish into what is now Guatemala in the 16th or 17th century. It came to what is now New England in 1606, brought by Captain John Mason, who went on to found the state of New Hampshire; though John Josselyn, in his 1672 list of plants suitable for the New World, reported sourly of the heat-loving, frost-tender shrub, “Rosemary does not thrive … [it is] no plant for this country.”
Nonetheless, rosemary made its way to present-day Saint Louis, Missouri with German immigrants from the duchy of Swaben, whose descendants until recently held a rowdy annual celebration in which a little boy and girl were crowned king and queen, the girl’s hair adorned with rosemary leaves. Fresh rosemary branches have also been used in some American Greek Orthodox Church congregations to scatter holy water in blessing; to decorate church icons (holy pictures); and as a ritual substitute for sweet basil (Ocimum basilicum) when the latter herb was not available.
HOW TO GROW ROSEMARY
Rosemary takes very well to indoor windowsill culture, requiring only a well-drained soil mix and full sun to bright shade. In summer, water regularly; in winter, water only when soil surface is dry; but at all times of the year, never allow water to pool around the bottom of the pot (more rosemaries are lost through overwatering than underwatering). Fertilize either with organic fish emulsion; a time-release fertilizer, such as Osmocote 14-14-14; or with a liquid 10-10-10 or 20-10-10 fertilizer every 5-10 times you water.
Do not let your plants become rootbound. (Yellowing basal leaves often indicate this.) To check to see whether a rosemary has outgrown its quarters, grasp the base of the central stem with one hand, gripping the container with the other hand. Invert the container, and shake gently until the plant eases out. If you find that the roots have filled or nearly filled the pot, transfer the plant to a container 2 inches greater in diameter than the old pot. Firm the soil carefully about the rootball, then water.
If your rosemary’s leaves start to brown and fall off, its roots are probably suffocating due to too much water in the soil medium.
Most rosemaries will not overwinter dependably in zones that get colder than 27ºF (Zones 9b-11). If you live where the temperature drops below freezing, you may:
- plant your rosemary in a portable container and bring it indoors when cold weather approaches;
- plant your rosemary outdoors in a spot protected from wind, wrapping it in burlap or heavy clear plastic when the thermometer dips to the danger mark;
- plant your rosemary in a deep well-insulated cold frame;
- or plant varieties reported as especially hardy (see below).
If you decide to give this herb a permanent spot outdoors in your garden:
- Dig a hole wide and deep enough for the roots to spread out.
- Using the soil you took out of the hole, make a mixture of 2 parts soil to 1 part well aged compost and 1 part coarse sand or fine gravel.
- Loosen the soil at the bottom of the hole with a garden fork.
- Sprinkle into the hole 1/2 cup of organic fertilizer (such as Happy Frog™ 5-5-5 All Purpose Fertilizer), and mix the fertilizer thoroughly with the soil at the bottom of the hole.
- Place the plant carefully in the hole, and fill the hole with the soil-compost-sand/gravel mixture mentioned above.
- Firm the mix gently around the crown of the plant — remember how fragile rosemary roots are — and water at once.
- Mulch with coarse compost or stones (small plant may be mulched with grass clippings) and keep moist but not soggy.
- If planting more than one bush, space them at least 3 feet apart.
In time you’ll be rewarded with the soft, light green needles that signal new growth. Don’t be discouraged if your rosemary doesn’t shoot up twelve feet the first week; they are slow, steady growers. Whether grown indoors or out, after rosemary flowers, trim the bush back several inches to stimulate new growth. (Rosemary plants also make good bonsai specimens, especially Rosmarinus officinalis var. prostratus, prostrate or creeping rosemary.)
COOKING WITH ROSEMARY
To harvest rosemary leaves for use in cooking, take cuttings in the early morning, when the essential oils in the leaves are at their freshest. (Never harvest more than a quarter of a given plant’s leaves at a time.) Either freeze the sprigs for future use (there is no need to blanch them first), or dry them as follows: Place cuttings on newspapers or screens in a dry, well-ventilated spot out of the sun. Strip the leaves off the stems when the needles are crackly-dry (1 to 3 days in New Mexico!), and store them in airtight containers out of the sunlight. (NOTE: If you are raising rosemary for use in potpourri or washing waters, the best time to harvest the leaves is when the plants are just beginning to come into flower.)
The French account rosemary as one of les fines herbes, along with basil, chervil, sweet marjoram, French tarragon, and thyme. Léonie de Sounin recommends French tarragon as a good flavor partner with rosemary. Rosemary goes particularly well with strong meats (such as the abovementioned lamb and kid), duck, turkey, roast beef, and salmon; with red wine and lemon juice rosemary makes a nice addition to chicken marinades; and rosemary branches make aromatic skewers for shish kabob.
TRADITIONAL USES FOR ROSEMARY
Modern herbalists recommend rosemary tea as a dandruff-preventative hair wash, as a mouthwash for sore gums, as an insect-repellent, and as a rub for sore muscles. The dried sprigs, hung in a closet, are said to discourage moths from eating clothes. Companion planting enthusiasts claim that rosemary planted next to cabbage, beans, and carrots will help to repel cabbage moths, bean beetles, and carrot fly. Rosemary is also said to thrive in the presence of garden sage (Salvia officinalis).
There are scores of rosemary cultivars in existence today, far too many to list here. We mention some of the most noteworthy below. There are two basic types: upright rosemaries (Rosmarinus officinalis), which can make multi-branched shrubs 1 to 6 feet tall depending on the variety (and the size of the pot into which they are planted); and prostrate or creeping rosemaries (Rosmarinus officinalis var. prostratus), which possess a spreading habit, growing much wider than they are tall.
All bloom approximately from January through April, and sometimes into summer and fall, particularly if trimmed back slightly after the first flush of flowering. All may be overwintered reliably on well-drained soils in full sun to light shade in USDA Zones 8-11. Protected from cold winds and drippy overhangs, and given very well-drained soil, various rosemary cultivars have survived winters in USDA Zone 7-11, and some cultivars have overwintered in Zone 6.
