Melissa officinalis
Lemon balm is a lemon-scented mint-family herb. Its soft leaves have a volatile citrus-herbal aroma that fades with prolonged drying and storage.1
It is related to mint and shares the family’s square stems and aromatic oils, but its characteristic note is lemon rather than menthol. In a Northeast garden it behaves as a hardy perennial, preferring sun and reasonably well-drained soil; left alone, it can spread from both seed and creeping stems.2
It is hardy to about USDA Zone 5, which explains why it can persist through much of the Northeast while still behaving like a soft, leafy herb in the kitchen. Pale flowers open above the foliage and attract pollinators; the leaves are the main food, but the flowers are edible too.2
The flowers are edible as well as the leaves, although the leaves carry most of the plant’s culinary identity. Its genus name, Melissa, comes from the Greek word for honeybee, a nod to the plant’s attraction for pollinators rather than to any honey in the leaf.2
Its lemon impression is not a single flavor compound but a blend of citrusy and floral terpenes, including citronellal, citronellol, citral, and geraniol. That combination accounts for the leaf’s simultaneous lemon, rose-like, and green-herbal qualities.3
