Sparganium americanum, also known as American bur-reed, is a perennial plant found throughout Eastern North America. Although when first observed the species looks like a grass, it is a type of bur-reed. American Bur-Reed is important for conservation purposes because the plant has the ability to remove nitrogen and phosphorus runoff from water like many other wetland species. By removing these elements from the water, American bur-reed protects waterways from excess nitrogen which can cause eutrophication. This increased nitrogen is especially a problem during the agricultural growing season when fertilizers are placed on crops. As fertilizer is being spread and adding extra nitrogen the ground water; American bur-reed is growing and taking up nitrogen. The genus name Sparganium is believed to have been derived from the Greek word sparganon, meaning "a band," a reference to the strap-like leaves. American bur-reed received its common name from the appearance of the 'burred' seed pods that are created after flowering.
American Bur-Reed currently does not have any commercial applications. However, in the natural world, the roots American bur-reed plant create stability along the shores of waterways and wetlands, and many types of water fowl feed on the seeds and foliage.
Within the realm of naturopathic medicine and folklore, American bur-reed does not have any known medicinal value.
Please note that MIROFOSS does not suggest in any way that plants should be used in place of proper medical and psychological care. This information is provided here as a reference only.
The roots and stems of American bur-reed are considered to be edible.

American bur-reed can grow in low marsh and shallow water, surviving in water up to 30cm deep. This species helps stabilize muddy areas and shorelines. American bur-reed live in peaty to sandy soils along lakeshores, slow moving streams and as floating vegetation in boggy lakes. The plant can survive in partial or full sun but is not drought tolerant and must stay in wet soil or submerged in water.

| Notes: |  |
American Bur-Reed is a monocot plant only having one seed leaf. Individual American bur-reeds can grow to be between 30cm to 200cm tall. American bur-reed plants produce white, rounded cluster, flowers during the summer months. The flower pedals could have a dark spot on them which may give the appearance of a darker flower. The flowers of the American bur-reed are monoecious meaning that individual flowers are either male or female and both sexes can be found on the same plant. American bur-reed flowers are pollinated by Wind. The leaves of the American bur-reed are acicular, green, and are triangular in cross section; the leaves of individuals plants living in deeper water can produce floating leaves. American bur-reed spread rapidly through their underground root systems of rhizomes. The fruit found on American bur-reed have a dull surface with beaks that are between 2 and 5 millimeters long. These beaks may be straight, but some of them may be curved. It should be noted that before the flowers or fruits are visible on the American bur-reed, the plant may be misidentified as a grass.
