Lemon Balm, scientifically known as Melissa officinalis, is a beloved herbaceous perennial plant belonging to the mint family (Lamiaceae).
Its most defining feature is the distinctive lemon scent and flavor. The leaves release a delightful lemony aroma when brushed or crushed, adding a refreshing citrusy taste to teas, desserts, salads, and drinks.
It has a fast growth rate and can spread vigorously by both seeds and rhizomes (underground stems).
Lemon Balm is incredibly easy to grow and requires minimal care once established, making it a perfect herb for beginner gardeners. Its vigor means you'll have a plentiful supply.

Lemon Balm is adaptable, growing well in full sun to partial shade.
Lemon Balm likes consistent moisture. Water regularly to keep the soil evenly moist, especially during dry spells or if grown in full sun.
It prefers well-draining, moist, fertile soil. While it can tolerate a range of soil types, including clay, it performs best in loamy, humus-rich soil. Ensure good drainage to prevent root rot.
Ideal temperatures range from 65°F to 75°F (18°C to 24°C).
