Often referred to as “the king of herbs” in France because of its huge influence on French cuisine, tarragon is one herb many can’t do without.
The highly aromatic plant has subtle undertones of anise, a spice in the same group as fennel, licorice, and parsley.

French and Russian tarragon are the herbs of interest.
French Tarragon
True French tarragon has the purer taste of the two. Its leaves are smoother, more shimmery, darker, and more pungent and aromatic than those of its Russian counterpart.
French tarragon is preferred for cooking over any other type because it delivers its strong, signature essence.
Lastly, you must propagate French tarragon vegetatively by division or stem cuttings because the seeds are sterile.
Russian Tarragon
Russian tarragon is taller, has pale leaves, and is bushier than the French type. It is also less aromatic and flavorful.
On the flip side, it is easier to find because it grows easily from seed and does not need to be intentionally planted.
