There's a stunning garden near me that has loads of Miscanthus varieties, block planted with prairie type plants. I went twice last year, going back in the autumn just to see the Miscanthus at their best and pick my favourites, as I am going to copy some of the ideas, though on a smaller scale
I like Miscanthus "Flamingo" which has a pinkish plume on it as I thought it wouls go nicely in my pink, purple & blue theme in the school garden I look after. I do like the look of "Silberfeder" however, but haven't much room in my own garden for that one.

I live in west central Scotland - not where that photo is...
