Deschampsia cespitosa 'Golden Dew'
Full sun or partial shade so would work well in a bit of a shady border. It is fairly fast growing and quite compact. It would look good spot-planted among perennials.
Remove the faded flower heads in late winter before new growth appears. If the foliage looks tatty then this can be cut back hard too. In warmer areas this grass will self seed freely.
Propagated by division.
