Expert Response

This looks like Yellow Nutsedge, a fairly common perennial weed. It will need to be manually removed (generally dug up rather than pulled up, since digging can more fully remove the roots) or treated with herbicide. There are not many herbicide ingredients that work well on nutsedges, but you can find recommendations in the linked page. More than one application might be needed before the plants fully succumb, but follow all product label directions for any herbicide you use.
