Cattails, also known as Bullrush or Corndog grass, are wetland plants typically 1 to 7 m tall. They have spongy, strap-like leaves and starchy, creeping stems (rhizomes), and the root systems help to prevent erosion. The plants themselves are often home to many insects, birds and amphibians. They grow along lake margins and in marshes, often in dense colonies. Cattail have a wide variety of parts that are edible to humans, and can be a source of ethanol. They do not require much, if any, maintenance.
I took this photo with my Canon Rebel XSI, slight editing using Lightroom 2. I found these cattails around the corner from my house, just off of the trail around Mundy Pond.
