Hello. Could you please tell me if you have seen flowers and berries on this vine? If so, what color were they?


Thank you for the information.

Yes late summer very small light purple flowers. No berries

This is black swallow wort and is on the Michigan invasive plant list, so it is not a nice plant and will take a multi year effort to control it. For the best instructions and education on this plant you can google Michigan Invasive Species-Best Control Practices, Black swallow wort. Good luck!
