Unless you consider sedge ornamental, it is a weed. In fact it is very hard to get rid of it as it grows from a "nut" often deep under ground and spreads enthusiastically.
Name: Daisy I Reno, Nv (Zone 6b) Not all who wander are lost
Key word: enthusiastically
Which suggests (and rightly so) that this plant is excuberant in its endeavor to take over your yard (and happy to do so).
Life is not a journey to the grave with the intention of arriving safely in a pretty and well preserved body, but rather to skid in broadside, thoroughly used up, totally worn out, and proclaiming...."WOW What a Ride!!" -Mark Frost
