Bamboo looking plant
Sorry for the delay in responding. Your question seems to have fallen through the cracks. Your plant appears to be Japanese Knotweed (fallopian japonica) also referred to as Michigan Bamboo. This is an invasive weed that came from eastern Asio in the 1800s. Check out this information from MSU: https://www.michigan.gov/documents/dnr/knotweed_BCP_372280_7.pdf I would eradicate it before it blooms and produces seeds. It may take years to get rid of it completely. Good luck! Feel free to contact us again if you have further questions.
