Usually on mucky or peaty soils in swamps, such as river floodplains; sometimes a dominant tree, or merely scattered (as often in cedar swamps).

There is a patch of dense pubescence at the base of each leaflet. The terminal bud is ± prolonged, usually a bit longer than broad, whereas in our other species, except for F. pennsylvanica, the terminal bud is at least as broad as long.
