    In cold climates, you should grow fountain grass as an annual. However, it is common to have inconsistent growth with fountain grass. Warm-season grasses, such as fountain grass, won't start growing until mid to late spring or even early summer. If there are still no signs of life by late spring/early summer, chances are good that the plant did not survive winter and will need to be replaced.

    I just wanted to say Thanks to Nikki for that answer. At least now I don't feel I'm to blame for killing the fountain grass.

    Some good choices to consider here would be Mexican feather grass, broom sedge and Tall Tails fountain grass.

    This grass starts out shorter in the spring and gets taller after it flowers. When you bought it in late summer, it was at its full height. Give it some more time, and it should get taller.

    Cut it back in early spring prior to new growth. It is better to leave the foliage over winter for added protection. This article will also help: https://www.gardeningknowhow.com/ornamental/foliage/fountain-grass/fountain-grass-pruning.htm

    oops, forgot this part. Penesetum love heat and sun. Actually, as much sun as possible to keep the rich burgandy color. If the plant gets too much shade, it will lose the color and have a decided greenish cast.

    Pennisetum 'Rubrum' - Red Fountain Grass is deciduous with frost and "root hardy" to 20-25*. It is only evergreen in frost free areas. Waqshington spans 3 different USDA hardiness zones. Not knowing which zone you are in, it is my supposition that your plant is showing normal winter leaf dieback. If your teemps dip below 20-25*F on a regular basis or for extended periods of time, the plant will perish. Note, the above is for P. 'Rubrum' planted in the ground. Containered plants are generally 1 zone less hardy.
