This is one of the most identifiable aquatic plants that we have (see, Pickerel Weed and Water Lily). It will be found in still waters, and, at the sandy edges of ponds and lakes. A cluster of common pipe wart is aptly call, hat pins. The leafless flower stalk will be seen piercing out of the water, usually not much before the month of July. The stalks emerge from a submerged tuft of grass-like basal leaves.
