About

Nuphar advena (spatterdock or cow lily or yellow pond-lily) is a species of Nuphar native throughout the eastern United States and in some parts of Canada, as well as Mexico and Cuba. It is locally naturalized in Britain.

Where it grows

It is native to Canada (such as Nova Scotia), the United States, Mexico, and Cuba. It has been introduced to the United Kingdom.

Uses

The plant is used as food. The dried seeds can be eaten or ground to flour. Native Americans cooked the rootstocks and removed the rind to prepare the sweetish, glutinous contents in various ways.
