I couldn't understand why my answer wasn't here, thought i was going bonkers, but then realised its under your previous Q, lol.

Oops! I will get better!!

Not your fault, I'm just not keeping up!

Most ornamental grasses are very easy maintenance: my favourites are Imperata rubra (gorgeous deep red); Hakonechloa macra (both are deciduous), and Stipa tenuissima and Anemanthele which are evergreen. The website www.knollgardens.co.uk is very useful.
