This can be a love-it-or-hate-it plant.  It is robust and can cover a large area.  Consider where you are going to plant it, and avoid planting in areas where it could take over a community pond. While this plant meets the Florida Native Plant Society's definition of native (here when Europeans first arrived), the center of its range is the Mississippi River and its tributaries.  American Indians are known to have spread this plant given that it was a good, prolific food source once established.  They may have brought it to Florida. Water plant.

Grows well well north of its native range.  Documented in very southern counties with an outlier in Martin County -- that outlier is also unique in that it was collected near a cypress dome. Closely related to corn, this species has been crossed with maize to produce a corn that is resistant to Helminthosporium turcicum, the fungus that causes northern leaf blight  (Wikipedia). Listed as Threatened in Florida. Informal borders.

Understory tree, use as a background plant or screen.
