its a Gunnera.
they can get huge, depending on the species.

Yup definitely Gunnera, would need a better photo to i.d.

Hi, agree it's a Gunnera, most likely to be G manicata, thereis another species which gets to roundabout the same size, but is only frost hardy, whilst manicata is borderline fully hardy, Derek.

thank you all for your replies now I know what the plant is.I have a nice little spot for one in my garden that will accommodate it nicely

My 6foot something husband is dwarfed by gunnera
Amazing it makes all that growth each year!
