Tarragon or Dragon's-wort (Artemisia dracunculus) is a perennial herb in the family Asteraceae. Plants in this genus are frequently called Wormwood, but this species is usually known as Tarragon. A European cultivar of this species is used as a popular culinary spice. The species name "dracunculus" leads to the common name "dragon herb." It is native to a wide area of the Northern Hemisphere from easternmost Europe across central and eastern Asia to India, western North America, and south to northern Mexico. The North American populations may, however, be naturalized from early human introduction. In California it is found primarily in the southern half of the state, in the coastal mountains and Sierras. Tarragon grows to 120-150 centimeter tall, with slender branched stems. The leaves are lance-shaped, 2-8 centimeter long and 2-10 millimeter broad, glossy green, with an entire margin. The flowers are produced in small capitulae 2-4 millimeter diameter, each capitulum containing up to 40 yellow or greenish-yellow florets. Some sources refer to this plant as an unattractive weed. It is cultivated primarily for culinary purposes but also has some wildlife value.
