That looks more like some kind of grass since the leaves seem to be single and emerge all along the length of the stems. Can you post a closeup of the bottom of the stems/plant?

Rite o. Hope this helps. As far I remember the local moroccon salesman pointed at some large bamboo and was saying that this particular plant is the same :) Maybe he tricked me, who knows. Just would be funny to know if I carried all this way back home an exotic weed..

Thanks.

Not much better, but thanks for the effort. I think it's a grass but before you throw it out I would get someone else's opinion and/or plant it somewhere that it can really take root and get larger. If it stays the same, then it is not the plant the guy told you. Small bamboos do look a lot like grasses for the first couple of years. I am interested to know what it really is.
