Photographed in my yard, where it had been planted; it has since been eradicated (i think...).
Location is approximate. I am never sure about B. biternatum vs. B. dissectum, this looks like the former... comments welcome!
There are several plants along the Shepherd Nature Trail in Duke Forest, park at Gate C on NC 751. Location is approximate. Plants are between numbered stops 6 and 7 (and maybe other places too).
