What plant could this be please?

Am unable to take a photo, as I don't have a camera or cameraphone but:

it's rather similar to nettles (squarish stem, same sort of shape of leaves) but it has yellow flowers and those leaves are variegated (thick white markings going round the circumference of the leaf near the leaf edge).

Those leaves are sorta reminiscent of mint and lemonbalm iyswim - except there is no mint smell to them.

Hmm. Some kind of coleus? Not sure if they flower though. How tall is it, and what shape are the flowers?

Try looking up Lamium as one possibility. You'll need to look at several variants, as there are many, and they are ... variant !

Thanks.

That looks a lot like it, only its got yellow flowers.

Some of it is pretty low-growing (as in pretty much going along the ground) and then there are some taller bits (with those flowers on) and they are about 2' - 3' high.

Definitely sounds like the yellow archangel. It looks just like a nettle, and has yellow flowers. Some varieties are variegated.

Another vote for Lamium. We used to have one in the back garden with white marking on the leaves and yellow flowers. Good ground cover - i.e. it really spreads !
