Petals can be seen to be a light purple-blue when they first blossom. As they become mature plants they become a light blue, or can even be white.[3]Due to its blue-white color, it is also known as “Blue Cloud", and typically flowers between the months June and July. [4]

Description

The leaves of the N. gigantea are round and can grow out to 75 cm across and are sinuate and dentate. In botany, this means that their edges are toothed with pointed teeth, about 0.5 cm long. The apex of the lobes are rounded, however, the N. gigantea develop points in the space between the lobes from the rest of the leaf. The flowers are eminent, growing to about 25 cm across and stands 50 cm above the water.  The leaves of N. gigantea lie on the water and are generally thick giving them a leathery feeling but are also brittle. The stigma is very dense with papillae, covering the dorsal surface of the carpels.  [5][6]

Distribution and Habitat

The seeds of N. gigantea are eaten by the Australians. In Australia, the tubers are collected and roasted by Aboriginal women. The buds and flower stalks are collected and eaten as well. [7]N. gigantea was first introduced in England in1852. Three years later in 1855, Van Houtte fruited the species. Since 1865, N. gigantea has been observed to flower during the summer months in water because that is the optimum condition for the tubers to germinate.[8]
