Costmary (Tanacetum balsamita)
Costmary (Tanacetum balsamita) is a European perennial which was once used medicinally and then came to be popular in culinary recipes. It was once called Bible leaf, as people used leaves to mark their place in their Bible. The leaves have a bitter, minty taste and it also has a strong odour. You may need time to develop a taste for it so use it sparingly until it grows on you!
