Can anybody identify this plant for me? It was given to me by my young helper who saw it at a small nursery she visited that was full of unusual plants. It is in a small pot and the growth is very "twiggy" I think the shape of the leaves might be a clue- the new ones are a bright shiny green but appear to darken considerably when older - white/ grey on the underside. I did think of Corokia as I think I detect a spine on one piece of the lower growth but the shape of the leaves did not seem to fit....
