Blue Lotus
Nymphaea caerulea, known primarily as blue lotus (or blue Egyptian lotus), but also blue water lily (or blue Egyptian water lily), and sacred blue lily (or sacred narcotic lily of the nile), is a water-lily in the genus Nymphaea.
Its original habitat may have been along the Nile and other locations in East Africa. It spread to other locations, however, already in ancient times, like the Indian Subcontinent and Thailand.
