Nelumbo nucifera or Lotus

This is a lotus flower or Nelumbo nucifera. Lotus plants have beautiful flowers and are even more amazing as plants. Here is a short description from Wikipedia: Nelumbo nucifera.

Nelumbo nucifera, also known as Indian lotus, sacred lotus, bean of India, Egyptian bean or simply lotus, is one of two extant species of aquatic plant in the family Nelumbonaceae. The Linnaean binomial Nelumbo nucifera is the currently recognized name for this species, which has been classified under the former names, Nelumbium speciosum Willd. and Nymphaea nelumbo, among others. (These names are obsolete synonyms and are avoided in current works.) This plant is an aquatic perennial. Under favorable circumstances its seeds may remain viable for many years, with the oldest recorded lotus germination being from that of seeds 1,300 years old recovered from a dry lakebed in northeastern China. 

It has a very wide native distribution, ranging from central and northern India (at altitudes up to 1,400 m or 4,600 ft in the southern Himalayas), through northern Indochina and East Asia (north to the Amur region; the Russian populations have sometimes been referred to as "Nelumbo komarovii"), with isolated locations at the Caspian Sea. Today the species also occurs in southern India, Sri Lanka, virtually all of Southeast Asia, New Guinea and northern and eastern Australia, but this is probably the result of human translocations. It has a very long history (c. 3,000 years) of being cultivated for its edible seeds, and it is commonly cultivated in water gardens. It is the national flower of India and Vietnam.

The seeds, rhizomes, and stolons are edible.
