Lemon Balm (Melissa officinalis): Calming Herb for Tea and Pollinators

Overview

Lemon balm (Melissa officinalis) is a bushy, lemon-scented perennial herb native to southern Europe and the Mediterranean. Its bright green, heart-shaped leaves release a sweet citrus fragrance when brushed, and its small white flowers are a magnet for bees—hence the genus name Melissa (Greek for "honeybee").

Botanical Description

Clump-forming perennial 60–90 cm tall. Leaves are opposite, ovate, 3–8 cm long, toothed, bright green, with a strong lemon scent. Flowers are tiny, white to pale yellow, in axillary whorls, blooming June–August. Spreads by rhizomes and self-seeding; can be aggressive in moist, rich soil.
