Largely restricted to the Gulf Coastal Plain of the south-eastern United States, Macranthera flammea is native to the states of Alabama, Florida, Georgia, Louisiana, and Mississippi, ranging as far east as Bulloch County in eastern Georgia. It occurs in and around bogs, bayheads, creeks, ecotones, and seepage slopes from sea level up to above sea level.Ecology
Macranthera flammea flowers from July to October, and has adapted to flower prolifically following fires. The flowering period coincides with the arrival of ruby-throated hummingbirds in its range as part of their migration across the Gulf of Mexico.
