Lemon Balm
Melissa officinalis
Lemon balm's botanical name (Melissa, Greek for 'honey bee') reflects 2,000+ years of beekeepers rubbing it on hives — the volatile oils mimic bee orientation pheromones, helping a swarm settle into a new hive.
How to care for lemon balm
Plant in a confined bed — self-seeds aggressively and reverts to plain green from variegated cultivars. Cut to the ground after flowering for fresh tender foliage in fall. Pinch flowers as they form to extend leaf production.
