True French tarragon has long slender leaves on a thin wiry stalk, a spicy aniseed aroma and a subtle licorice flavour. Its lesser relative, Russian tarragon, has pale coarse leaves and not much taste at all. Then there is Mexican, a cousin of the marigold, with its bright yellow flowers and strong flavour - best avoided.
