These seems to be very well rooted and I'm not sure if this is the Japanese knotweed I read somewhere. I'm not sure if I ought to take care of them or say goodbye? Thanks for helping out this gardening novice! Cheers!
Flowering quince. A woody shrub nothing like the herbaceous Japanese knotweed. The most abundant large weedy knotweed here is Bohemian knotweed.
