We did find some Night Shade in one of our pastures a couple of weeks ago - some were still green and others already starting to turn black - we are located in Northeast Wisconsin. We found the Night Shade in a spot we have never seen it in before, we are seeing more of it this year than ever before maybe due to the dry summer?
I find it really likes to grow in spots that are overgrazed, dry, etc. I have a drylot behind my barn - I walked it the other day and pulled out all the night shade (with rubber gloves), it was the only thing growing there.
