Melissa officinalis aka Lemon Balm
Taxonomy
Lemon balm (Melissa officinalis) is a perennial herbaceous plant in the mint family native to south-central Europe, the Mediterranean Basin, Iran, and Central Asia, but now naturalised elsewhere. It is an aromatic green wonder that is very easy to take care of, with a long history as a medicine and cooking ingredient. It grows to a maximum height of 1 m (3 ft 3 in) and has a tetrahedral stem covered with short, gentle hairs. The leaves are petiolated, ovate or rounded-rhombic in shape, and have a mild lemon scent. From June to August, small white flowers full of nectar appear, and the plant bears shiny black seeds. It is not to be confused with bee balm (genus Monarda); although the white flowers attract bees, hence the genus Melissa (Greek for "honey bee"), it is grown as an ornamental plant, for its oil (to use in perfumery), and for its use as a herb, in teas and also as a flavoring. Lemon balm is often called an “elixir of life”, and its leaves and oils are commonly used in herbal medicine and as a flavoring.
