Lemon basil (Ocimum x citriodorum) belongs to the Lamiaceae (the Mint family). It is an annual herb that is a hybrid between basil (Ocimum basilicum) and American basil (Ocimum americanum). This herb is grown primarily in northeastern Africa and southern Asia for its strong fragrant lemon scent, and is used in cooking. It can reach 20-40 cm in height. The leaves are narrow ovate, glossy and opposite with slightly serrated edges. The white labiate flowers bloom in the spikes in late summer to early fall. Lemon basil is a popular herb in Arabic, Indonesian, Lao, Malay, Persian and Thai cuisine.
