Lovage is an upright perennial herb in our zone (7) The taste and smell are reminiscent both of celery and parsley only more intense and spicy than either. The seeds can be used in the same way as celery seeds. Lovage compliments a large number of foods. The leaves can be used in salads, soups, and anything containing pork, poultry, and strongly flavored fish but be careful since it's quite powerful. The young leaves are the most widely used part which can be picked in spring and summer and have a mild, sweet celery flavor with a hint of aniseed. The young stalks can also be blanched like celery, cooked or candied like angelica, and the seeds can be used in baking. Even the roots are edible.
