(Alisma subcordatum) is a common shoreline colonizer that grows well on exposed mud flats in water less than 1 foot deep. Water plantain is a perennial herb that supports broad, flat leaves that grow 1-2 feet high. Tiny white flowers are spread out on a highly branched flower stalk. Like arrowhead, water plantain has many ecological values. The sturdy flower stalk offers a popular perch for songbirds and insects. A variety of waterfowl consume both tubers and nutlets. Water plantain also provides juvenile fish rearing habitat and shoreline buffering.
