Don't get me wrong, I love lemon balm (Melissa officinalis). Add a few leaves to iced tea, or throw into a pot of mint or green tea, and it infuses your beverage with its delicate lemon flavor. You can also make a simple syrup with the leaves, mix with water and pour over ice for a refreshing "lemonade". I once even made lemon balm pesto with lemon balm leaves, garlic, and olive oil and tossed it with linguine.
However, lemon balm is in the mint family, and you know what that means- it spreads like the dickens! So much so that I am now constantly pulling up entire plants (at least I hope I am getting the entire plant) as they spread around the Garden. What was once planted simply on either side of the gate has now overrun the oregano, despite the fact that oregano does a pretty good job of spreading on its own! This year, to help curb the spread by seed, I took matters into my own hands.
