Lemon balm is a perennial herb that grows 50 to 80 centimeters tall. It has a square, often branched, and sparsely hairy stem. The opposite leaves have petioles of varying lengths; they are broadly ovate to heart-shaped and have an irregularly notched or serrated margin.

The dark green upper surface of the leaves is slightly hairy and has a distinctly prominent venation. The pale white flowers are about one centimeter in size and are arranged in small, semi-whorled clusters in the leaf axils.

The flowers and crushed leaves have a spicy, aromatic scent strongly reminiscent of lemon. The scent comes from the essential oils contained in glandular scales on the upper surface of the leaves. As a perennial plant, lemon balm can survive even cold winters thanks to its underground rhizome. In the garden, it tends to spread vigorously.
