Original post maybe barberry (sometimes called firethorn)? Fine thorns but very plentiful. Small leaves, sometimes reddish but there are green varieties I think. Going mostly by the color. The other is pokeweed, I hate them. Messy plants. My son likes to whack plants with a stick (future swordsman), I told him he can whack all of these he can find.
Fire bush or Burning Bush for sure. Not Autumn Olive or pokeweed. I have the stinkin' stuff all over my farm. Seems the previous owner liked it as a shrub. Now it's on the fence lines and spreading across the pasture. 2-4D won't kill it and neither will Round Up. I'm gonna try triclopyr next. The prickly stuff has red berries that the birds eat then they crap them back out when they are sitting on a fence and it grows and becomes entangled with the wire. I hate it with a passion.
