You can keep Lemon Verbena in the kitchen on the counter for a couple of days. Eventually it will begin to dry up.

The best way to store Lemon Verbena is by drying it. Dry in a bunch no more than 1" in diameter thick. Hang upside down in a warm, dry place (indoors or outdoors) until the stems are brittle and snap when bent. You want the plants to dry as quickly as possible, as this will decrease molding. Once dry, store in an airtight container in the pantry.
