See reply in duplicate thread. It's Miscanthus sinensis, and looks like a fine-bladed cultivar, either a smaller one or not yet mature.

Cut it back to just above any new shoots. Rake out the crown lightly after cut-back to remove detritus.

Get some photos in bloom, later in the year, and we can probably narrow down the ID.

I agree with donn. The gold color looks awesome.

If you don't cut it down, you will literally hear it "crackle" & "pop" as the new chutes grow into the old ones. It's pretty cool. I used to love hearing it during the spring.

I have been hearing the crackle and pops outside. I thought I was going crazy because couldn't find what it was from. It's my grass?! Thanks for all the advice. I plan to cut it this week to a few inches from the ground. How fast will it grow back and how tall? We like it for privacy. Thanks again

Be sure to check the height of the new shoots, and don't cut it back deeply enough to cut them.

It should grow 6-12" taller than it was last year, and will probably grow more blossoms.

Depending on weather and water availability, it will take 2-3 months to reach maximum foliage height, and then will add height with the blossoms, anywhere from mid-late summer.
