I found this fern.. tree? I'm curious as a beekeeper whether or not these are a viable source of pollen or nectar.
Albizia julibrissin, silk tree or often called mimosa, though it is not a Mimosa species. It is a good source of nectar, but considered an invasive species in your region.
It's not likely that M. pigra is growing in North Carolina. Be attentive when researching this re: honey. As Eric stated, it often has the common name of mimosa, but the scientific genus Mimosa is different.
