Rosemary (Salvia rosmarinus, also known as Rosmarinus officinalis) is a shrub belonging to the mint family, Lamiaceae. It features fragrant, evergreen leaves that resemble needles, and its flowers are typically purple, though they can also be white, pink, or blue. Native to the Mediterranean region, the plant has many cultivars and its leaves are often used for flavoring food.
The plant’s root system is fibrous. It grows as an aromatic evergreen shrub with leaves similar to those of Tsuga needles. Forms can be upright or trailing; upright types reach about 1.2 to 1.8 meters (4 to 6 feet) tall. The evergreen leaves are 2 to 4 centimeters (3/4 to 1.5 inches) long and 2 to 5 millimeters (1/16 to 3/16 inch) wide, green on top and white underneath, covered in dense, short, woolly hairs. In temperate climates, rosemary flowers in spring and summer, but in warm climates it may bloom continuously. Flowers appear in groups of two or three along the branches and can be white, pink, purple, or deep blue. The plant sometimes flowers outside its usual season, known to bloom as late as early December or as early as mid-February in the Northern Hemisphere. Rosemary can live up to 35 years.
A closely related species is Salvia jordanii (formerly Rosmarinus eriocalyx), native to Iberia and the Maghreb of Africa.
Carl Linnaeus first described the species in 1753 as Rosmarinus officinalis. In 2017, based on molecular phylogenetic evidence, it was reclassified into the genus Salvia, reviving a name first published in 1835 by Fridolin Karl Leopold Spenner. Because the name Salvia officinalis was already taken, Spenner used Salvia rosmarinus as a replacement. Linnaeus cited Rosmarinus from an earlier work by Gaspard Bauhin, whose second edition appeared in 1671.
The botanical name combines two Latin words, *ros marinus*, meaning “sea-dew,” as noted by Elizabeth Kent in her 1823 work *Flora Domestica*. The earliest classical use of the Latin word is attributed to Columella.
Rosemary is native to the Mediterranean region, as well as Portugal and northwestern Spain. It was naturalized in China as early as 220 CE, during the late Han dynasty. It likely reached England with the Romans in 43 CE, but no records confirm its presence there until the 8th century, in a document later credited to Charlemagne, who promoted herb cultivation and ordered rosemary grown in monastic gardens and farms. The first record of naturalization in Britain dates to 1338, when cuttings were sent to Queen Philippa by her mother, Countess Joan of Hainault, and planted at the old palace of Westminster. After that, rosemary appears in most English herbal texts. It arrived in the Americas with early European settlers in the early 17th century and later spread to South America and globally.
The plant is reasonably hardy in cool climates. Cultivars like 'Arp' can survive winter temperatures down to about −20 °C (−4 °F). It withstands drought and can survive long periods without water. It is considered potentially invasive. Its seeds are often difficult to start, with low germination rates.
Because it is attractive and drought-tolerant, rosemary is used as an ornamental in gardens and for xeriscape landscaping, especially in Mediterranean climates. It is easy to grow and pest-resistant. It can grow quite large and remain attractive for years, and can be pruned into formal shapes, low hedges, or topiary. It grows well in pots. Groundcover cultivars spread widely with a dense, durable texture. To harvest from the plant, the bush should be 2 to 3 years old to ensure it is large enough, and no more than 20% of the growth should be taken to preserve the plant.
Numerous cultivars have been selected for garden use, including 'Albus' (white flowers), 'Arp' (upright, light green leaves, lemon-scented, cold-hardy to 10°F), 'Aureus' (yellow-speckled leaves), 'Benenden Blue' (narrow, dark green leaves), 'Blue Boy' (dwarf, prostrate, small leaves), 'Blue Rain' (pink flowers), 'Golden Rain' (green leaves with yellow streaks), 'Gold Dust' (dark green leaves with golden streaks, stronger than 'Golden Rain'), 'Gorizia' (upright, much larger leaves), 'Haifa' (low and small, white flowers), 'Irene' (low and lax, trailing, intense blue flowers), 'Lockwood de Forest' (procumbent selection from 'Tuscan Blue'), 'Ken Taylor' (shrubby), 'Majorca Pink'/'Majorca' (pink or light purple flowers, upright with long twisting branches, cold-hardy to 15°F), 'Miss Jessopp's Upright' (tall, fastigiate, wider leaves), 'Pinkie' (pink flowers), 'Prostratus' (low groundcover), 'Pyramidalis' (or 'Erectus') (fastigiate, pale blue flowers), 'Remembrance' (or 'Gallipoli') (from the Gallipoli Peninsula), 'Roseus'/'Roseus-Cozart' (pink flowers), 'Salem' (pale blue flowers, cold-hardy similar to 'Arp'), 'Severn Sea' (spreading, low-growing, arching branches, deep violet flowers), 'Sudbury Blue' (blue flowers), and 'Tuscan Blue' (traditional robust upright form).

Lore & Background
The epithet officinalis could not be used because Salvia officinalis already existed, so Spenner used Salvia rosmarinus as a replacement. The plant was considered sacred to ancient Egyptians, Romans, and Greeks, and was written about by Pliny the Elder and the ancient Greek botanist Pedanius Dioscorides in De materia medica.
Reader's Guide
Rosemary is significant as a culinary herb, ornamental plant, and cultural symbol. Its leaves are used fresh or dried to flavor stews, roasted meats, marinades, and herbal tea. Rosemary extract, containing carnosic acid and carnosol, is approved as a food preservative (E392). The plant is drought-tolerant and used in xeriscape landscaping, especially in Mediterranean climates. It is easy to grow, pest-resistant, and can be pruned into formal shapes or low hedges. Cultivars such as 'Arp' withstand winter temperatures down to about −20 °C. In culture, rosemary is associated with remembrance: in Shakespeare's Hamlet, Ophelia says, 'There's rosemary, that's for remembrance.' Mourners toss sprigs into graves, and in Australia, rosemary is worn on ANZAC Day because it grows wild on the Gallipoli Peninsula. Hungary water, one of the first alcohol-based perfumes in Europe, was primarily made from distilled rosemary.

Rosemary in Herbes de Provence
Rosemary occupies a prominent position in Herbes de Provence, a spice blend rooted in Provençal culinary tradition. The mixture pairs rosemary with thyme, marjoram, basil, and bay leaf, with lavender appearing as an occasional additional note. Within the European category of pre-mixed seasonings, this blend represents one of the most widely recognized herbal combinations available to home cooks. The practical logic behind such mixes is straightforward: when a recipe calls for several dried herbs in combination, having them already blended saves the cook from measuring each one separately. Grocers have traditionally stocked these ready-made blends, though the same combination can be assembled at home from individual dried herbs for later use. Rosemary's presence in the Provençal mix distinguishes it from other European blends like fines herbes, which relies on parsley, chives, tarragon, and chervil, or the various seasoned salts, giving the Provençal blend its own distinct herbal identity within the broader landscape of European spice mixes.
Rosemary in Italian Seasoning
The Americas version of Italian seasoning offers a different window into rosemary's role in blended spices. In this North American formulation, rosemary is paired with thyme, basil, and oregano to create a ready-to-use herbal mix. Interestingly, the European iteration of Italian seasoning takes a different composition—oregano, thyme, basil, parsley, and sage—leaving rosemary out entirely. This regional divergence highlights how the same named blend can carry different herbal profiles depending on where it is produced and consumed. The convenience factor remains the same in both versions: a cook seeking that familiar Italian-herb flavor can reach for a single pre-mixed packet rather than sourcing four or five individual herbs. Whether purchased from a grocer or blended at home for future recipes, the American Italian seasoning positions rosemary as one of four equal pillars of the blend, granting it a more prominent role than in many other European mixes where it is either absent or one of many components.
The Practical Tradition of Blended Spices
Rosemary's appearances in spice mixes are part of a much larger culinary tradition: the blending of multiple herbs and spices into a single, convenient seasoning. The core idea is practical—when a recipe requires a specific combination of dried ingredients, pre-mixing them streamlines the cooking process. This tradition spans continents and cuisines. In the Americas, blends range from pumpkin pie spice (cinnamon, clove, ginger, nutmeg, allspice) to Old Bay (celery salt, black pepper, red pepper flakes, paprika). In South Asia, masalas combine dry-roasted spices or form pastes with garlic, ginger, onions, and tomato. In the Middle East, mixes like baharat and ras el hanout serve similar unifying functions. Rosemary fits into this global pattern as one herb among many that benefits from being pre-combined with its partners, making complex flavor profiles accessible to any home cook without requiring a full spice cabinet at hand.
Rosemary's Position in the European Blend Taxonomy
Within the European category of spice mixes, rosemary appears in a limited but meaningful number of blends. Herbes de Provence includes it alongside thyme, marjoram, basil, and bay leaf, with lavender as an occasional addition. The American version of Italian seasoning features rosemary as one of four herbs. By contrast, other European blends—fines herbes with its parsley, chives, tarragon, and chervil; quatre épices with pepper, cloves, nutmeg, and ginger; mulling spices with cinnamon, cloves, allspice, nutmeg, and dried fruit; sharena sol with summer savory, paprika, and salt—do not call for rosemary at all. This selective inclusion places rosemary in a specific subset of European blends, distinguishing it from the sweet-spiced mixes like mulling spices and the delicate-herb combinations like fines herbes that populate the same category. The availability of these mixes both pre-made from grocers and as home-blended preparations means that rosemary's role in European seasoning is largely defined by which particular mix a cook chooses to reach for.
