Are the white boxes significant? Looks like they are pointing out two grasses: Muhlenbergia rigens and Festuca glauca. The fescue will need more irrigation than the deer grass. Perhaps this is an opportunity for native grasses?

Forest, to be honest, somehow I didn't notice the boxes until the post was already up. (I must have written this one late at night). And didn't notice the second grass until then either. And I think you're right. It is festuca or a carex. I suspect the designer put patches of that in to provide walking paths. I would have just put in strips of pathing stones instead. The festuca just detracts from the gorgeous deer grass.
