Fountain Grass (Pennisetum setaceum)

Fountain grass is a common name for Pennisetum setaceum, an upright perennial grass with narrow leaves and bristled, plume-like flower heads. Its look varies among forms, and the name Pennisetum remains common even though UF/IFAS notes that Cenchrus setaceus is the currently accepted taxonomic name in some treatments. [UF/IFAS Center for Aquatic and Invasive Plants](https://plant-directory.ifas.ufl.edu/plant-directory/pennisetum-setaceum/) ## Identification and placement The species is native to North Africa and the Middle East and has been widely planted as an ornamental in warm regions. UF/IFAS describes tufted, erect stems and terminal panicles; this general profile does not describe every named cultivar. Use the clumping foliage and airy seedheads as a textural accent in an appropriate landscape setting. ## Regional caution Fountain grass is invasive in some regions. UF/IFAS reports impacts in South Florida and other locations, including displacement of native plants and increased fire frequency and intensity; Hawaii and Nevada list it as a noxious weed. Check local invasive-plant rules before planting, and avoid moving seedheads or contaminated soil from affected sites. ## Maintenance Remove spent or unwanted seedheads before they disperse where the species is invasive, and clean tools, clothing, and equipment after work in infested areas. Gloves are sensible because the source notes that leaves and seedheads can irritate skin.
