Do you need height?

Preferably 3-4 ft. but something shorter might do!

This one could work--I have it and love it!

'Karl Foerster' Feather Reed Grass
Grows 3-5'
Hardy to Zone 5
Showy blooms w/ a purple tint

I also think flame grass could give you the colors you want provided you need 4-5' in height. Good luck!

Thanks! I think the flame grass may be perfect for the spot I neet to fill.

For bronzey or purple foliage, consider Panicum virgatum 'Shenandoah' or Miscanthus purpurascens.
