Grass Garden Types ?

I have a small flower bed I want to completely replant next spring , as it is a mess of shrubs I don't like and a Golden Hop which has gone berserk ! I do like ornamental grasses , but know very little about them.
Looking around Beetham Nursery this weekend they had a very good selection of Pennisetum (Panicum ?) - fountain or feather grasses . These really took our eye . But on doing my Google research on them , it seems they are not fully hardy in our climes. Now I don't want the faff of bringing them under cover every winter . Any advice on these or other showey grasses would be appreciated.
TIA

I picked up a grass variety, which I've been hankering after for some time, recently at a trip to RHS Wisley. Commonly called "Japanese Forest Grass", but the variety I went for is, "Hakonechloa macra 'Aureola’". It does die back in Winter, but should come back with both barrels blazing next year
Be aware though that several varieties exist (the Head Gardener from Canterbury Cathedral put on an amazing show of them at Hampton Court this year (yes, I was there too but all his samples were sold and only on offer via the web).

Naturally, asking the forum is going to give you a variety of favourites, preferences and suggestions; so, do research each suggestion so that you get, not only the best deal for your pound sterling, but also year round robustness!

 

Thanks for the pointer @"M" the forest grass does look very nice . Any more ideas anyone on ornamental grasses ?
