Tarragon Herb
Also knoum as Estragon. From the family Compositae.
A native of southern Europe, tarragon is now found in dry areas of North America, Southern Asia and Siberia. Dracunculus' means little dragon. Its naming could have occurred (via the Doctrine of Signatures) as a result of the shape of its roots, or because of its fiery flavor. Whatever, it was certainly believed to have considerable power to heal bites from snakes, serpents and other venomous creatures.
In ancient times the mixed juices of tarragon and fennel made a favorite drink for the Kings of India. In the reign of Henry VIII, tarragon made its way into English gardens, and the rhyme, 'There is certain people, and certain herbs, that good digestion disturbs,' could well be associated with tarragon. I love, too, the story that Henry VIII divorced Catherine of Aragon for her reckless use of tarragon.
Species
Artemisia dracunculus
French Tarragon
Half-hardy perennial. Ht 90cm (3ft) spread 45cm (1 Sin). Tiny, insignificant, yellow flower heads are borne in sprays in summer but rarely produce ripe seed sets except in warm climates. The leaves are smooth dark green, long and narrow, and have a very strong flavor.
Artemisia dracunculus dracunculoides
Russian Tarragon
Hardy perennial. Ht 1.2m (4ft) spread 45cm (18in). Tiny, insignificant, yellow flower heads in sprays in summer. The leaves are slightly coarser and green in color, their shape long and narrow. This plant originates from Siberia, so is hardy.
Cultivation
Propagation
Seed
Only the Russian variety produces viable seed. A lot of growers are propagating and selling it to the unsuspecting public as French tarragon. If you really want Russian tarragon, sow the small seed in spring, into prepared seed or plug trays, using the bark, peat, grit compost. No extra heat required. When the young plants are large enough to handle, transfer to the garden, 60cm (24in) apart.
Cuttings
Both French and Russian tarragon can be propagated by cuttings.
Roots: Dig up the underground runners in spring when the frosts are finished, pull them apart; do not cut. You will notice growing nodules; these will reproduce in the coming season. Place a small amount of root - 8-10cm (3-4in) -each with a growing nodule, in a 8cm (3in) pot, and cover with compost. Use the bark, grit, peat mix and place in a warm, well ventilated place. Keep watering to a minimum. When well rooted, plant out in the garden after hardening off, 60cm (24in) apart. It is possible to take softwood cuttings of the growing tips in summer. You will need to keep the leaves moist, but the compost on the dry side. It works best under a misting unit with a little bottom heat 15°C (60°F).
Division
Divide established plants of either variety in the spring.
Pests and Diseases
Recently there has been a spate of rust developing on French tarragon. When buying a plant, look for tell tale signs - small rust spots on the underneath of a leaf If you have a plant with rust, dig it up, cut off all foliage carefully, and bin the leaves. Wash the roots free from soil, and pot up into fresh sterile soil. If this fails, place the dormant roots in hot water after washing off all the compost. The temperature of the water should be 40-46°C (105-115°F); over 46°C will damage the root. Leave the roots in the hot water for 5 minutes then replant in a new place in the garden.
Maintenance
Spring: Sow Russian tarragon seeds if you must. Divide established plants, fake root cuttings.
Summer: Remove flowers. Autumn: Pot up pieces of French tarragon root as insurance.
Winter: Protect French tarragon. As the plant dies back into the ground in winter it is an ideal candidate for either agricultural fleece, straw or deep mulch.
Garden Cultivation
French Tarragon has the superior flavor of the two and is the most tender. It grows best in a warm dry position, and will need protection in winter. It also dislikes humid conditions. The plant should be renewed every 3 years because the flavor deteriorates as the plant matures.
Russian tarragon is fully hardy and will grow in any conditions. There is a myth going around that it improves the longer it is grown in I place. This is untrue, it gets coarse. It is extremely tolerant of most soil types, but prefers a sunny position, 60cm (2ft) away from other plants.
Harvest
Pick sprigs of French tarragon early in the season to make vinegar. Pick leaves for fresh use throughout the growing season. For freezing it is best to pick the leaves in the midsummer months.
Container growing
French tarragon grows well in containers. Use the bark, grit mix of compost. As it produces root runners, choose a container to give it room to grow so that it will not become pot bound. At all times make sure the plant is watered, and in the daytime, not at night. It hates having wet roots. Keep feeding to a minimum; overfeeding produces fleshy leaves with a poor flavor; be mean. In winter, when the plant is dormant, do not water, keep the compost dry and the container in a cool, frost-free environment.
Culinary
Without doubt this is among the Rolls Royces of the culinary herb collection. Its flavor promotes appetite and complements so many dishes - chicken, veal, fish, stuffed tomatoes, rice dishes, and salad dressings, and of course is the main ingredient of Sauce Bernaise.
