The true French tarragon prized in classical French cuisine. Critical fact: French tarragon does NOT set viable seed in Australia (or anywhere). Any 'tarragon seed' you find for sale is Russian tarragon (A. dracunculus var. inodora), which has inferior flavour. True French tarragon can ONLY be propagated by division or cuttings. It struggles in hot, humid climates and is best suited to cool-temperate and Mediterranean zones.
