I had no idea there was different tarragons.
Then I started looking to see which one I had in my spices it is the french tarragon,
Artemisia dracunculus.
The Russian is,
Artemisia dracunculoides Pursch
Then here in Texas of we have our own substitute that is all so often here with plants.
Mexican Marigold Mint (Tagetes lucida)
Here is a link I found about the three.
