Palustris I did find a grass for sale on Ebay but when I looked up info on Google it called it an invasive grass, that's what got me worried about buying any old grass without recommendation. Thanks for the warning of the name, I wouldn't have known that.
Teresa, I had a look at the names you gave and I really like the Rubrum, I remember we had that in our garden when I was a child, so I'm off to Google now to see where I can get one from.
Thanks both. :)
