French tarragon, and Russian tarragon are two VERY different plants. True French t. will blow the socks off of the Russian variety. What you buy in the supermarket labeled as "French T." may, or may NOT be the real Mc Coy (many commercial growers just add the word " French" to what they are selling to supermarkets because that is what the consumer wants, and the produce manager doesn't know the difference). I neither own, nor have any interest in any 'seed company', but I would strongly suggest you go to any reputable seed company and buy "one offering" of real live plants ONCE of the real Mc Coy. Bring plants inside and put them in the kitchen window sill, or whatever you need to do to keep them alive through your winter, and enjoy a fine herb forever. You may freely take cuttings of your "true" plant forever. You will never regret your initial outlay.
