Giant knotweed

Observation - Giant knotweed - UK and Ireland. Description: Shape of leaf base and length of leaves (25cm)suggest giant knotweed but it is covered in bristly hairs on stem and upper and lower leaf surfaces. I haven't found any reference to this character for giant knotweed. Perhaps it's a hybrid?
