As gardens fade and kitchens fill with the smell of holiday roasts, one herb stays green and fragrant all winter long. Our November Herb of the Month is rosemary, the evergreen herb of memory, comfort, and hearty cold-weather cooking.

Meet the Herb: Rosemary

Rosemary is a woody, evergreen shrub with narrow, needle-like leaves that are deep green on top and silvery underneath. In late winter and spring it bursts into small flowers in shades of pale blue, violet, pink, or white. Brush your hand across it and you’ll release its signature scent: piney, resinous, and slightly lemony, with a hint of camphor. A member of the mint family, it was officially reclassified in 2017 as Salvia rosmarinus, making it a close cousin of garden sage.

A Fascinating History

Rosemary grows wild on the rocky coasts of the Mediterranean, and its old Latin name, ros marinus, means “dew of the sea.” Ancient Greek students reportedly wore rosemary garlands while studying, believing it sharpened the mind. That reputation stuck: Shakespeare’s Ophelia offers “rosemary, that’s for remembrance,” and for centuries sprigs were tucked into wedding bouquets as a symbol of fidelity and laid on graves as a sign that loved ones would not be forgotten.

From Garden to Kitchen

Rosemary’s bold flavor holds up to long cooking, which makes it perfect for November menus. Try it with:

• Roasts: lamb, pork, chicken, and the holiday turkey
• Vegetables: roasted potatoes, root vegetables, squash, and mushrooms
• Breads: focaccia, dinner rolls, and savory scones
• Pairings: garlic, lemon, olive oil, thyme, and sea salt

A little goes a long way, so chop the leaves finely or add whole sprigs and remove them before serving. Sturdy stems make fragrant skewers for grilled vegetables.

Traditional Wellness Uses

Folk healers used rosemary to ease indigestion, soothe aching muscles, and lift tired spirits. Modern researchers are curious too. Rosemary is rich in antioxidant compounds such as rosmarinic acid and carnosic acid, and small studies suggest that simply smelling its aroma may give memory and alertness a modest boost.

A note on safety: Rosemary is safe in the amounts used in cooking. Concentrated forms are another matter. Avoid large medicinal doses if you are pregnant, have epilepsy, or take blood thinners, and always dilute rosemary essential oil before applying it to skin. Never swallow the essential oil, and check with your doctor before using any herb as a remedy.

Grow Your Own

Rosemary thrives on a little neglect. Give it what it loved on those Mediterranean hillsides:

• Sun: at least 6 to 8 hours of direct sunlight a day
• Soil: sandy, fast-draining soil; in pots, use a cactus or gritty mix
• Water: let the soil dry out between waterings, since soggy roots are its biggest enemy
• Winter: most varieties survive outdoors in USDA zones 7 to 10; in colder areas, grow it in a pot and bring it indoors to a bright, cool window

Because rosemary is evergreen, you can harvest fresh sprigs all year. Snip the soft, green tips with clean scissors, and never remove more than a third of the plant at once. Regular trimming keeps it bushy.

Did You Know?

• Rosemary often blooms in the middle of winter, making it a precious food source for bees when little else is flowering.
• Rosemary extract is used commercially as a natural preservative, helping keep oils and meats from going rancid.

This November, tuck a sprig into your roasting pan, keep a pot on a sunny sill, and let rosemary bring a little Mediterranean warmth to the colder months.
