The copper grass at the back of the photo...I have had this grass for 3 years(I don't even know it's name...shame on me). I really love it as it holds it's colour all year. It has been in the same container for the last 3 years & is now starting to look 'spidery'. It produces seeds around Autumn, can these be re sown or does it need to be transplanted to a bigger container?

Any help greatly received
