Lemon balm (Melissa officinalis), not to be confused with bee balm (which is genus Monarda), is a perennial herb in the mint family Lamiaceae, native to southern Europe and the Mediterranean region.
It grows to 70–150 cm tall. The leaves have a gentle lemon scent, related to mint. During summer, small white flowers full of nectar appear. These attract bees, hence the genus name Melissa (Greek for 'honey bee').
