Good effort on the photos; they really help to get a good idea of what kind of plant the bittersweet is. I also thought that your sketch is impressive. Good work Mcyr.

Well done, Mcyr.
Looks like you found something suspicious. It is amazing how that plant seems to find a way to get to the light, growing and winding its way through a fence. I wonder if eventually the plant will break through the fence as it continues to grow.

Sketch and photos are great.

Impressive sketch!

The leaves and growth habits of this one make me want to agree with you that this is invasive bittersweet. Did you see any of last year's berries hanging on to notice whether the ovary walls are yellow or white?
