I have been calling these zebra grass ever since I had them but shirley tulip has thrown me in to disarray!!
She has suggested they are not zebra grass at all & having looked at pics of those I can only presume mine are imposters pretending to be something they are not!!
Actually the stripes of z.g are not like mine at all so what are they?
The only thing I could find similar is a Phalaris?

Thank you all for your IDs & comments. These spread very quickly & different conversations on GoY have shown they can be a menace to some people! I must admit I have re-planted some by the rockery & you can hardly see the rocks now!! :o///
