Melissa is a
genus of five species of
perennial herbs native to
Europe and
Asia. The name
Melissa is derived from a Greek word meaning bee, owing to the abundance of nectar in the flowers which attracts bees. The stems are square, like all other plants in the
mint family. The leaves are borne in opposite pairs on the stems, and are usually ovate or heart-shaped and emit a lemony scent when bruised. Axillary spikes of white or yellowish flowers appear in the summer.
