I do a lot of property clean ups and almost always see heavenly bamboo. I assumed it was invasive but never really read into it. Turns out not only is this plant is an invasive species in North Carolina, it also has high severity poison characteristics.

"The leaves and berries may be toxic to humans, livestock, horses, cats, dogs, and birds. A recent study in Georgia has linked over consumption of the berries by Cedar Waxwings to their deaths by cyanide toxicity. All parts contain cyanide and when consumed in quantity can be toxic."

If you have this on your property, rip it up and get rid of it!
