The French consider Tarragon to be the "King of Herbs." It is one of the five herbs in the classic French combination called "fines herbes," which you may have seen at your local grocery or in your cookbooks. There are two main types of tarragon grown as culinary herbs, French Tarragon and Russian Tarragon. The latter is less popular and said to be less flavorful, so most tarragon you'll find at your local greenhouse is the French variety.
