Broadleaf pond lily

Description:

Also known as yellow pond lily or spatterdock, it is native to the eastern US. Spatterdock was long used in traditional medicine, with the root applied to the skin and/or both the root and seeds eaten for a variety of conditions. The seeds are edible, and can be ground into flour. The root is edible too, but can prove to be incredibly bitter in some plants.
