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.

Listed as Endangered in Florida. Please acquire only from reputable nurseries. The US range is limited to Florida. Globally, it is also found in the West Indies. Accent shrub, screen plant if used as a hedge.

Very thorny. In the northern parts of its range, a thornless cultivar is planted. Specimen tree. To avoid insect issues, best not to plant in large numbers.

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.

Informal shady semi-shady gardens.

Rare. Listed by the FACS as Threatened.  Please acquire only from reputable dalers with appropriate permits. Screen or buffer plant. Specimen shrub.

Understory shrub.

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.

Specimen plant, typically forms clumps of stems,the young fan-shaped fronds hide the principal stems. The lower fronds can be removed so that the trunks can be clearly seen. Sometimes used as a street tree.

They are included here because they are valuable to insects and because they are lovely and good to have in a native garden if you are lucky enough to have them naturally.   Data on culture has been assumed from where this grows in nature -- it is not typically grown and no reliable data appears to be available. Can parasatize southern pines leading, in heavy infestations, to loss of vigor. Retain in semi-natural gardens.

Use as a specimen plant or understory tree. May be single or multi-stemmed.

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.

It's a legume, so nitrogen fixation may help it survive in low nutrient soils. Fast growing. Shade tree. Attractive for its lacy foliage. Does well as a street tree.
