Field Notes
The day was breezy and overcast. It was late fall and was very cold. We were happy to find our plant, Oriental Bittersweet, climbing the fence. We saw our plant rustling in the wind with the smell of a wet wildlife section blocked off for plants to grow in between the athletic fields. The Bittersweet had reproduced in many areas and we found 2 or 3 bunches in one area.We were surprised to find many bunches of Oriental Bittersweet that had completely taken over small areas. When we came back the next day and realized some of the bunches were dying out. We were lucky to see the root on one of the many plants. In the two days we were excited to find Oriental Bittersweet.

Supporting Evidence

We found Oriental Bittersweet climbing the fence in between the athletic fields. The vines were very bumpy, woody, and round because it was fall.

We found a "bush" of Oriental Bittersweet on the rocks. We found that the red berries had a yellow skin like they red berries had hatched out of the yellow skin.

The leaves that we found were very glossy and round. They grew up to around 2 1/2 inches. All the leaves had clear ridges on the edges just like teeth.

I saw your sketch of the best of VS sketches page (http://vitalsignsme.org/best-sketches) and I had to come check out your observation. Nice work!!

And great photos...

Did you by any chance count the number of seeds that were emerging from the yellow skins? This can be useful in confirming which species you saw. There most common bittersweet in Maine is the invasive, but there is a native (American bittersweet) and a hybrid.

thanks for publishing your observation!
