From Johnny's Selected Seeds:
 
Aromatic leaves are a substitute for French tarragon.
Sweet licorice flavor brightens salads and main dishes. The edible, pretty, golden-yellow flowers bloom all summer. Thrives in warmer climates where French tarragon will not grow. Also known as sweet mace or Mexican tarragon.

• Edible Flowers: Use the flowers to garnish desserts and drinks with the same sweet licorice flavor as the leaves.
