Fountain Grass (Pennisetum)

*Pennisetum* is a horticultural genus of ornamental grasses with substantial variation among species and named selections. Plants sold under this name may differ in mature size, flower color, bloom season, foliage color, hardiness, and growth habit, so this genus-level record should not be used to predict the traits of a particular cultivar. The [University of Wisconsin Extension species profile](https://hort.extension.wisc.edu/articles/fountain-grass-pennisetum-alopecuroides/) illustrates that variation within fountain grasses and discusses one commonly grown species. ## Growing Conditions Choose care for the exact species or cultivar rather than assuming a single sun, water, or soil requirement applies across the genus. Many ornamental fountain grasses are grown for narrow foliage and soft, brushlike flower plumes, but timing and color vary. ## Landscape Use Fountain grasses are used for texture and movement in borders and larger plantings. Check the species or selection record for mature dimensions and suitability before placing it near paths or other plants. ## Maintenance Follow the care guidance for the identified species or cultivar. Where a particular grass is deciduous, old foliage is commonly cut back in late winter or early spring; do not apply that practice to every member of the genus without checking its needs.
