Cattails aka Punks and Corndog Grass, Typha latifolia are aquatic or semi-aquatic, rhizomatous, herbaceous perennial plants that is found in a variety of wetland habitats. It makes a great pond plant and we have them in our pond. Many parts of the Typha plant are edible to humans. Before the plant flowers, the tender inside of the shoots can be squeezed out and eaten raw or cooked.The rhizomes are edible. Evidence of preserved starch grains on grinding stones suggests they were already eaten in Europe 30,000 years ago.
