Melissa officinalis

Lemon balm (Melissa officinalis) is a perennial herbaceous plant in the mint family. It grows to a maximum height of 1 m (3+1⁄2 ft) and the leaves have a mild lemon scent. During summer, small white flowers full of nectar appear. The species is native to Eurasia and naturalised elsewhere. The leaves are used as an herb, in teas and as a flavouring. It is grown as an ornamental plant and for its oil (to use in perfumery). It has been cultivated (and used to attract honey bees) since at least the 16th century.
