Field Notes
It was September here in Bangor. Our Science class went out to investigate around the school to see if we found any invasive species. We looked around to see if there were any, and lo and behold, we came across something we believe is Woody nightshade. Some evidence that what we found is woody nightshade, is the stem. The stem is slim that is tinted purple and a wood type material, yet flexible. To add to this, when we crushed the stem it reviled an unpleasant and strong smell. Like as if you sprayed too much Febreze in one room after someone went to the bathroom. The leaves were shaped like an arrow and around the edges was a smooth and wavy looking pattern. The leaves were arranged in an alternate order and had dark purplish parts dappled along the leaves. The plant itself was a vine that came down from a different kind of plant I believe is called Virginia Creeper. The berries were colored in a range from red to green to orange, some even yellow. It was attached by a brownish purple stem along the vine itself.
Supporting Evidence
Photo of my evidence.
In this photo, the leaves reveal a dark green color with a purplish tint. They come in a shape similar to an arrow. They have a smooth and wavy shape.
Photo of my evidence.
In this photo, we see 3-10 berries. We believe these are the berries of the woody nightshade. The berries come in red, orange, green, and some even yellow. They come in a distinct egg shape.

In this photo, the stems are thin and have a wood-like look to them. The stem is also a very flexible stem and easy to break in half. We even crushed the stem to find an unpleasant and strong smell.

I like the way you described the way it smelled when you guys snapped the stem. You guys also took good pictures!

Great work, hedgehog-- you did find solanum dulcamara. This is a high quality observation with impressive detail about the leaf shape, arrangement, and color, and great information on the stem, too.

Keep up the great work and keep observing!


Thank you! We appreciate this feedback a lot.
