Little Dragon: French Tarragon Botanical Illustrations and Photographs


Summary: French tarragon botanical illustrations and photographs display forms, not flavors and fragrances, of roots, shoots and unreliable flowers and seeds.

French tarragon botanical illustrations and photographs authenticate alleged serpent-like roots on the flowering herbaceous perennial even though only actual plant parts avow allegedly anise-like, bittersweet, celery-like, licorice-like and minty flavors and fragrances.
French tarragon botanical illustrations and photographs broach the fruits, leaves, roots, seeds, stalked inflorescences and stems that proper light, moisture and temperature bring to temperate soils. The names drakon, dracunculus and tarkhum communicate respective Greek, Roman and Arab cultural conveyances of the "little dragon" from central, east, Mediterranean, Russian and Siberian Asia. French tarragon, anecdotal antidote for venom and talisman against dragons and snakes, delivers anise-, celery, licorice-, mint-like dashes to garden displays and salad and soup dishes.
Such flavors and fragrances emerge far less effectively and enduringly from tarragon varieties with duller, lighter, rougher leaves and taller, wider growth habits than French tarragon.

French tarragon botanical illustrations and photographs furnish growth habits and habitat niches for the Asteraceae aster, composite, daisy, sunflower family member of eight- to 10-year lifespans.
French tarragon gets the scientific name Artemisia dracunculus var. sativa (Artemis's little dragon variety cultivated [not wild-growing]) for reproductive growth by cuttings and division, not seed. It has coiled roots for harboring trace alkaloids and for holding the 1.5- to 3.0-foot- (0.46- to 0.91-meter-) tall and wide mature sub-shrub in well-drained soils. French tarragon, investigated scientifically in 1753 by Carl Linnaeus (May 23, 1707-Jan. 10, 1778), is intolerant of inundated soils and of pH ranges except neutral 6.5-6.9.
Soil moisture beyond wrung-sponge consistencies in the upper 5-inch (12.7-centimeter) layer and temperatures below 5 degrees Fahrenheit (minus 15 degrees Celsius) jeopardize French tarragon life cycles.

Methyl chavicol inside plant tissue and 2-inch (5.08-centimeter) mulch 2 inches from French tarragon stems to drip lines under stem ends keep away pests and weeds.
Coumarins as blood-thinners and methyl chavicol as cancer-causing estragole limit day-in, day-out lacing of fish, poultry, salads and soups with French tarragon's essential oils-laden, fresh leaves. Dark, glossy, lance-like, smooth, 0.79- to 3.15-inch- (2- to 8-centimeter-) long, 0.79- to 3.94-inch- (2- to 10-centimeter-) broad leaves maximize processed and raw flavors and fragrances. Weak-oiled mid-summer through fall foliage nips nicely into bundles for cool, dark drying; containers for darkened, sealed storage; and dishes as fall through winter holiday condiments.
French tarragon botanical illustrations and photographs sometimes observe rare occurrences of green-yellow inflorescences June through August and non-viable, 0.024- to 0.039-inch- (0.6- to 1-millimeter-) long seeds.

French tarragon unpredictably produces dense, flat floral clusters, presented botanically as capitula (little head-like objects), each 0.08 to 0.16 inches (2 to 4 millimeters) in diameter.
French tarragon botanical illustrations and photographs queue each cluster's 20 to 40 green-yellow disk florets, each 0.24 inches (0.6 millimeters) long, on 0.5-inch- (1.5-centimeter-) long stalks. Ever-sterile seeds and oftentimes sterile flowers regale French tarragon with impractical, infrequent, intriguing aesthetics even though reproduction results only from cutting stems or from dividing roots. Success suggests separating serpentine root balls into quarters for late winter soils and slicing stems to 6-inch (15.24-centimeter) lengths for late spring-, early summer-potted sandy soils.
French tarragon botanical illustrations and photographs transmit the standard looks, not the signature flavors and fragrances, of ever-present roots and shoots and rare-occurring flowers and seeds.
