Tarragon: A Bit of Botany
a bit of botanical information on tarragon

description
Artemisia dracunculus is a species of perennial herb in the family Asteraceae.

Tarragon grows to heights of 4-5 feet, with slender branched stems. The glossy green leaves are lanceolate with an entire margin, and grow 2–8 cm long and 2–10 mm wide. Tarragon produces flowers in small capitulae 2–4 mm diameter. Each capitulum contains up to 40 yellow or greenish-yellow florets.

Some tarragon plants produce seeds that are generally only sterile, while others produce viable seeds. French tarragon, seldom produces any flowers or seeds. Tarragon has rhizomatous roots and can readily reproduce from these rhizomes.

go for the french
Tarragon comes in two varieties, Russian and French. The former has less oil—and therefore, less flavor—so tarragon almost always implies the French Plant.

Russian tarragon may be grown from seeds, but the more desirable French variety must be propagated from cuttings or root divisions. Divide the roots in spring and plant 1-inch pieces of their tips. Or take cuttings in summer, thin plants to 2-foot spacing.

French tarragon is a perennial with a creeping, serpentine root, and stems that reach 2 feet. Its leaves look like a larger version of rosemary. This herb rarely flowers, and if it does, the fruits are sterile.

Tarragon grows best in rich, well-drained soil under full sun. Make sure the roots do not become waterlogged. If your winter temperatures drop below the teens, mulch well each fall. Divide tarragon roots every few years to retain plants vigor.

Tarragon leaves bruise easily. Harvest them carefully in early summer. Because tarragon loses medicinal value when dried, freeze the fresh herb or preserve it in vinegar.

Tarragon is best known as the main seasoning in bearnaise sauce.
