The coolest looking blue berries drew my attention to this weedy plant the first time I saw it when taking a walk near the Conestoga Creek. I was reminded of that Autumn day trip to Lancaster County, Pennsylvania a number of years ago when I recently spotted the same kind of plant scrambling along a cement bridge in Snyder County, PA.

Right away I could see its vine-like nature and that its leaves were triangular. The vine had climbed from a stream bank up and over the top of the bridge and down onto the guard rail.
The vine appeared to be growing well and it seemed to be liking its sunny spot very much as many small white flowers were present.
Triangular leaves and pink stems with thumb-tearing spikes. Don’t try to weed out this plant without a sturdy pair of gloves on your hands!
