    Root rot can easily kill ornamental grasses. Try pulling on the leaves at the base of the plant. If they pull out easily, it may have died off.
    Clean up the plant and wait it out.

    You can cut them back now. This will help the new growth. If is fortunate that you will have this extra time in the season for growth, as here in my area it has been excessively cold this winter. It is just now finally warming up!

    Go ahead and cut them, and let them continue growing.

    Unfortunately, all varities of fountain grass should be considered potetially invasive.

    https://www.unce.unr.edu/publications/files/nr/2002/FS0250.pdf

    "While the nursery varieties are said to be sterile, there is no clear evidence that they will not add to the spread of fountaingrass. Several varieties of Pennisetum setaceum may be sold, ranging in color from reddish to rose or purple. All cultivars are considered invasive and should not be sold or planted."

    Too bad, because its beautiful. Don

    Our experts say you can stimulate new growth by feeding your plant with a slow-release balanced fertilizer.

    You are on the border (8a) of its hardiness zone (9 and higher) so if you did not provide extra winter protection, it wouldn't come back in your 8a zone.

    If it has been coming back, you may have had milder winters. In any case, it sounds like it is time for a replacement.

    You certainly could have a problem with this. These grasses can become invasive. It's low-maintenance and would look attractive there but could cause problems later. You may want to consider an alternative.

    Bring purple fountain grass inside a frost-free area that stays above 40 degrees F (4.4 C) or inside a cool room in the home. Cut it back and water carefully during the winter. Don't let it dry out, but be sure not to overwater.
