A lot of people plant Calendula or Pot Marigold (Calendula officinalis) in their veggie gardens to keep the pests away.  It definitely has a potent, but not unpleasant scent to it and has both astringent and antibacterial properties. These healing properties make it a perfect candidate for drying and using as a healing "gardener's salve" to put on hands that have been digging in the garden without gloves, or have perhaps been a little overzealous in a blackberry patch.
