While it’s not particularly attractive, tarragon (Artemisia dracunculus) is a hardy herb commonly grown for it’s aromatic leaves and peppery-like flavor, which is used for flavoring many dishes and is especially popular for flavoring vinegar. Tarragon herb plants should be grown in areas receiving full sun. Space tarragon plants approximately 18 to 24 inches apart to ensure adequate air circulation. They should also be located in well-drained, fertile soil. However, these hardy plants will tolerate and even thrive in areas having poor, dry or sandy soil. Tarragon has a vigorous root system, making it quite tolerant of arid conditions. Established plants do not require frequent watering, outside of extreme drought.
