Melissa officinalis

Lemon balm, Melissa officinalis, is a robust herbaceous perennial grown for its aromatic foliage, which can be used in desserts and to make a revitalising herbal tea. In the summer months it produces small white flowers that are a hit with bees. Use a small handful of fresh leaves, then steep and strain to make tea that can be enjoyed hot or iced.

Like mint, it's a particularly rampant grower, so is best confined to a raised bed or container where it can't spread too much.

For best results, grow Melissa officinalis in moist, well-drained soil in full sun or partial shade. Cut back after flowering to promote fresh growth and prevent seeds from forming.
