I made this observation on my way to the start of the Alder Trail, where I think I saw black swallowwort last year. I was sad to see the suspicious plant on both sides of the road here. There was more on the sunnier side of the road, the side with the truck and boat. There were plenty of old stems and the remains of old seed pods (they looked like grey, dried out, opened pods of a similar shape to milkweed pods, but narrower and more delicate) mixed in with the weeds, so this plant was apparently here last year as well. There is, for Monhegan, a fair amount of truck/ vehicle travel along this road. I wouldn't be surprised to learn that this contributed to the spread of this species along the length of the road.
This photo shows the dark color, five short and fat petals, and small size of the flowers, which are characteristic of black swallowwort flowers. This image also shows the opposite arrangement of the leaves on this plant, another characteristic of black swallowwort.
This image shows the old vines from last year being lifted up by this year's growth. You can also see the tall, reaching, curling ends of the plant that makes them look like they'd be great climbers (black swallowwort is a climbing vine). This image shows the oppositely arranged leaves, which is a characteristic of black swallowwort. And finally, you can see that the leaves are fat blades/ elongated, pointy ovals, which is the shape of black swallowwort leaves.
