This appears to be a shrub, stays green all year..can’t tell if it’s Poison Sumac??
no, it is not poison sumac. It is actually an invasive non native shrub called Chinese privet, Ligustrum sinense. The following link says there is something poisonous about it, but I have never heard this and even if it has some poisonous qualities, it is in no way as damaging as poison sumac, a swamp plant.
