Is it French or Russian Tarragon?

[Gmcd]

Hi, I brought a Tarragon plant from a garden center today, I asked the lady if it is French or Russian but she didn't know as they were just labled "Tarragon" from their supplier. It has quite a stong almost pepperminty sweet smell and taste, it does give a very slight numbing effect but for me it doesnt have the distinctive anise taste that I have read about. Anyone know what Russian Tarragon tastes and smells like?
