About

Nymphaea () is a genus of hardy and tender aquatic plants in the family Nymphaeaceae. The genus has a cosmopolitan distribution. Many species are cultivated as ornamental plants, and many cultivars have been bred. Some taxa occur as introduced species where they are not native, and some are weeds. Plants of the genus are known commonly as water lilies, or waterlilies in the United Kingdom.

How to grow it

Water lilies are not only decorative, but also provide useful shade which helps reduce the growth of algae in ponds and lakes and some species are keeping in aquariums. an example is nymphaea lotus. Many of the water lilies familiar in water gardening are hybrids and cultivars. These cultivars have gained the Royal Horticultural Society's Award of Garden Merit:

'Escarboucle' (orange-red)

Safety

All water lilies are poisonous and contain an alkaloid called nupharin in almost all of their parts.

Where it grows

Nymphaea has a cosmopolitan distribution and is found almost all over the world, apart from New Zealand and the pacific slope of North America. It occurs in freshwater, as well as brackish water habitats. Water lily species often have a very wide distribution.
