I have been googling images of it but it's not quite the same as what it in my garden.

The stems are red, a very deep red with no other colour or shading whatsoever. They are not bamboo like (no line around the stem where each leaf stems off), where the leaves appear it's smooth and uninterrupted along the entire length. The stems are more woody, sapling-like and not hollow.

It has not flowered at all.

The leaves are heart shaped and quite large, but are now taking on the weathered and damaged appearance of a dock leaf.

I spotted this plant several months ago and is has not grown much at all since.

It's longest stem is about 4ft.

I would post a pic but it's dark now.

Any clues anyone?
