Please help to identify this plant in South Surrey, BC, Canada. It's tall (taller that 6 feet) and I think it's invasive. Thank you!
Wow. It was fast! THANK YOU SO MUCH! Macleaya My neighbor gave it to me and now I don't know how to get rid of it. It's everywhere.
Yes, I've grown a fair number of invasive plants but the spread rate of this one is really impressive!
