Tarragon
Artemisia dracunculus
Tarragon (Artemisia dracunculus) is a perennial herbaceous plant in the family Asteraceae, prized worldwide for its distinctive anise-like flavor and aroma. Also known as estragon or dragon herb, tarragon is one of the four French "fines herbes" (alongside chervil, parsley, and chives) and is indispensable in French cuisine.
• Belongs to the large and diverse genus Artemisia, which includes wormwood (A. absinthium), mugwort (A. vulgaris), and sweet wormwood (A. annua)
• The specific epithet "dracunculus" is Latin for "little dragon," possibly referring to the serpentine shape of its roots or its coiled rhizomes
• Two principal cultivated varieties exist: French tarragon (A. dracunculus var. sativa) and Russian tarragon (A. dracunculus var. dracunculoides)
• French targoon is considered vastly superior in flavor and is the preferred culinary variety
• Russian tarragon is hardier and more vigorous but has a weaker, less refined flavor
• Native range extends from southern Russia and Siberia through Central Asia to Mongolia and western China
• Also indigenous to parts of eastern Europe, the Caucasus, and scattered regions of western North America
• Has been cultivated in Europe since at least the Middle Ages; records of its use date to the 8th century
• French tarragon does not produce viable seeds and is propagated exclusively vegetatively, suggesting it has been maintained in cultivation through human selection for centuries
• The plant was introduced to the Americas by European colonists and has naturalized in some regions of the United States and Canada
Root System & Stems:
• Slender, creeping rhizomes spread horizontally, enabling the plant to form dense clumps over time
• Stems are erect, smooth to slightly grooved, branching in the upper portions, green becoming somewhat woody at the base
• Rhizomatous growth habit is key to the plant's persistence and vegetative propagation
Leaves:
• Alternate, linear to lanceolate, 2–8 cm long and 2–10 mm wide
• Entire (smooth-edged), glossy, dark green on the upper surface
• Covered with minute glandular trichomes that produce the characteristic essential oils
• Aromatic when crushed — the scent is reminiscent of anise or licorice due to the compound estragole (methyl chavicol)
Flowers & Reproduction:
• Small, inconspicuous flower heads (capitula) arranged in loose panicles
• Each flower head is only 2–4 mm in diameter
• French tarragon rarely, if ever, produces fertile seeds — it is effectively sterile and must be propagated by division or cuttings
• Russian tarragon does produce viable seeds, though they are considered inferior for culinary use
• Flowering period is typically mid to late summer (July–September in the Northern Hemisphere)
Fruits (Russian tarragon only):
• Small achenes (dry, single-seeded fruits) ~1 mm long, typical of the Asteraceae family
• Prefers open, sunny locations with well-drained, moderately fertile soil
• Naturally found on dry grasslands, rocky slopes, riverbanks, and disturbed ground
• Tolerant of poor, sandy, or gravelly soils but performs best in loamy, well-drained substrates with a neutral to slightly alkaline pH (6.5–7.5)
• Drought-tolerant once established; does not tolerate waterlogged or heavy clay soils
• Hardy in USDA zones 4–8 for Russian tarragon; French tarragon is slightly less cold-hardy (USDA zones 5–8)
• Attracts pollinators when in bloom, including small bees and hoverflies
• The strong aromatic compounds in the foliage deter many herbivorous insects and browsing animals
Light:
• Full sun is ideal (at least 6 hours of direct sunlight per day)
• Can tolerate partial shade but will produce less aromatic foliage
Soil:
• Well-drained, moderately fertile soil; avoid heavy, waterlogged substrates
• pH range of 6.5–7.5 is optimal
• Adding sand or grit to heavy soils improves drainage
Watering:
• Water regularly during the first growing season to establish roots
• Once established, tarragon is moderately drought-tolerant
• Avoid overwatering — soggy soil leads to root rot
Temperature:
• Optimal growing temperature: 15–24°C
• French tarragon dies back in winter and regrows from rhizomes in spring
• Mulching in colder zones helps protect rhizomes from hard frosts
Propagation:
• French tarragon: division of rhizomes in spring or softwood cuttings in early summer — never from seed
• Russian tarragon: can be grown from seed sown indoors in late winter or directly outdoors after the last frost
• Division every 3–4 years helps maintain plant vigor and prevents overcrowding
Common Problems:
• Root rot from overwatering or poorly drained soil
• Rust (Puccinia tanaceti) can affect foliage in humid conditions
• Aphids may occasionally colonize new growth
• French tarragon purchased as "seed" is almost certainly the inferior Russian variety — always buy French tarragon as plants or divisions
Culinary Uses:
• One of the four classic French "fines herbes" — essential in French cuisine
• Key ingredient in Béarnaise sauce, tartar sauce, and vinaigrettes
• Used to flavor chicken, fish, eggs, and vegetable dishes
• Fresh tarragon has a more intense flavor than dried; add toward the end of cooking to preserve aroma
• Tarragon vinegar is made by steeping fresh sprigs in white wine vinegar
• Used in pickling cucumbers ("dill pickles" sometimes include tarragon)
• Pairs well with lemon, mustard, and cream-based sauces
Traditional & Medicinal Uses:
• Historically used in European folk medicine as a digestive aid and appetite stimulant
• Chewed to relieve toothache — the essential oil has mild analgesic properties
• Used as a traditional remedy for intestinal worms and menstrual irregularities
• Contains estragole (methyl chavicol), which has been studied for anti-inflammatory and antioxidant properties
• In some cultures, used as a mild sedative or sleep aid
Other Uses:
• The aromatic foliage is used in potpourri and sachets
• Sometimes planted as a companion herb to repel certain insect pests
• Used in the production of some liqueurs and herbal infusions
Fun Fact
The name "tarragon" has a fascinating etymological journey through multiple languages: • The Latin "dracunculus" means "little dragon" — a reference to the plant's coiled, serpentine rhizomes • The Old French "estragon" and the Medieval Latin "dracunculus" both reflect this dragon association • In Arabic, tarragon is called "tarkhūn," and it has been used in Middle Eastern cuisine and medicine for centuries • Some medieval herbalists believed tarragon could cure snakebites, reinforcing the dragon-serpent connection French vs. Russian Tarragon — A Culinary Tale: • French tarragon (var. sativa) is essentially a clone — it has been propagated vegetatively for centuries and is genetically uniform • Russian tarragon (var. dracunculoides) grows readily from seed but has a coarser, less refined flavor that dissipates quickly when dried • A simple test: crush a leaf and taste it — French tarragon has a pronounced, sweet anise flavor; Russian tarragon tastes bitter and grassy Estragole — The Flavor and the Controversy: • The primary aromatic compound in tarragon is estragole (methyl chavicol), which constitutes up to 70–80% of the essential oil • Estragole gives tarragon its characteristic anise-like aroma and flavor • In very high doses, estragole has shown carcinogenic potential in rodent studies, leading to regulatory scrutiny • However, the amounts consumed in normal culinary use are considered safe by food safety authorities Tarragon and the Art of French Sauce-Making: • Béarnaise sauce, one of the great French mother sauces, is essentially a tarragon-flavored derivative of hollandaise • The sauce was reportedly created in the 19th century at the restaurant Le Pavillon Henri IV near Paris • Without fresh tarragon, authentic Béarnaise simply cannot be made — it is the defining ingredient
