Lemon balm, a member of the mint family, is a lovely mild herb named for the lemony scent of its leaves. Originally grown in South Europe, lemon balm is often used in combination with other herbs and is frequently found in poultry and fish dishes, desserts, and teas. It also makes a nicely scented sachet. Plant one at the edge of a gate so that when the gate opens and closes the lemony scent fill the air. Like other types of mint, it likes to spread, so a container is a great choice.
