Perennial plant id

Can anyone help identify this perennial? It's in my sister's garden - she can't remember from last season if it is herbaceous or hardy but the flowers close at night and has become beautiful ground cover. I thought it might a Coreopsis but the foliage seems a little too compact and broad in shape for that.
Ah thank you fidgetbones - hadn't thought of that!
