Schoenoplectus pungens Three Square Bulrush
General
An emergent wetland plant commonly found in shallow standing water. Can tolerate periods of drought and complete inundation. Three square bulrush can have rhizomatic spread, and is capable of forming colonies and recovering from damage in this way. Formerly thought to be the same species as Schoenoplectus americanus, and the two plants are easy to mistake for one another. Will provide cover, food, and nesting material for small birds.
Plant Description
Growing in shallow water up to 4' tall. The flowers are spikelets that grow in small clusters usually up to 5 each, appearing to emerge from the side of the stem (the continuation of the "stem" is actually a bract). The stem is triangular and has two or three sheath leaves growing from the base of the plant, and two or three alternate leaf blades growing higher on the plant.
