When I plan gardens, I often choose herbs that seem to taste great together and try to create a nice arrangement for a ready-made herb tea garden. This is a great idea for a farmers market item and can be designed in a single pot. Because tea herbs can and should be snipped often, they do not outgrow the pot like a single larger plant might.
Lemon balm is usually a regular plant in any herb tea garden I make. Lemon balm is loved by everyone and makes a great tea, either hot or cold.
