This water-lily is native to the Nile River and East Africa, while now having spread throughout Africa all the way to the Cape region. Occasionally referred to as the Blue Lotus, it is not related to the actual Sacred Lotus of India though. The flowers, having a diameter of 8-15 cm, are borne on long stalks which emerge from the water surface and remain open during daytime.
The petals are light-blue on top and whitish below. This species is relatively hardy and thus commonly cultivated. There are several plants residing in the pond of the Mangrove House.
