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.

Benefits from controlled burns. There are contradictions in herbarium databases, and reliable observations in counties where there are no herbarium specimens. Probably native in low abundance in dry (xeric) native grasslands and open pinelands throughout the state. Makes a colorful contribution to a native plant meadow. Becomes darker (more purple) after pollination. When flowering, the stem needs support from surrounding plants. It is primarily a fall bloomer.

Edible, very hot fruits
