Does anyone know what kind of decorative grass this is along my fence line? I have an area that needs to be filled in and don't want to plant the wrong kind!

Are you sure that's grass and not Daylilies?
Some close ups might help.

Looks like daylilies to me also.

Yes they are day lilies. I wasn't sure if the grass grew along with the lilies or if it was something seperate added to the bed. So if I plant some new bulbs the grass will also come in?

You've lost me

You need to remove the grass from the bed manually and create an edge to keep it from coming back. I doubt there is room for any bulbs among those daylilies. They should start blooming soon, and you might like them.

Thanks everyone. I actually want the grass that's pictured. I have about a 3 ft gap where it's not growing. I just wasn't sure if the grass would come in from the lily bulbs or if it was something that was planted additionally as "filler".

Daylilies do not grow from bulbs and they will continue to spread by rhizomes. They can be dug and divided as needed.
