Did you ever consider walking down the aisle clutching a bundle of garlic and dill?
Well, if you're a stickler for tradition, you might want to think about it. Until modern times, brides did carry garlic and dill. The practice probably originated from the time of the Plague, when people clutched the herbs over their noses and mouths in a desperate effort to survive.
Survivors of great tragedy can affix tremendous protective powers to anything that has provided comfort, and the herbs made it into the ceremony marking renewal. Over time, brides added better-smelling flora to the arrangement, and a whole dictionary of meaning arose to define each type of blossom.
