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.

Red/orange fall color is excellent. Leaves have three separate shapes: ovoid, tri-lobed, or mitten-shaped (left or right). Mature trees tend to have fewer lobed leaves. Subject to laurel wilt disease.  Please be careful not to move firewood or dead wood around.  Best not planted in areas where laurel wilt is present. A relatively small tree that often forms thickets. Best used in informal settings.

Understory tree, use as a background plant or screen.

Specimen shrub. Fine foliage. Does well adjacent to structures or woods.

Use along streams or edges of retention areas. Can be a screen or specimen tree in moist areas. Blooms better in moderate to high light settings.

Some literature sources suggest that this species may have some salt tolerance as it apparently grows along the upper edges of some salt marshes, but so far as we have seen recorded, not in Florida. Moist/wet wildflower garden.

In a managed garden, gamagrass can be trimmed back at the end of winter. Hedge, foundation planting, individual large grass clump, background screen for a flower garden. Rain garden or bioswale.
