Rich deciduous forests (and northern hardwoods), especially in moist places, but occasionally in drier oak-hickory forests; swamps and streamsides.
This is a variable species, perhaps even more so than others in the genus, but it does not seem worthwhile to apply names to the variants. It is a much commoner and more widespread white-flowered species than G. laciniatum, though the petals in both usually dry ± yellowish. The small heads, prominent white petals, and tendency to trifoliolate leaves will help in identification. The slender puberulent pedicels have at most a few long hairs intermixed, in contrast with those of G. laciniatum. One collection from Delta Co. has a glandular beak on the fruit, as in G. macrophyllum.
