The most well known of the Pennisetums, Pennisetum setaceum ‘Rubrum’, commonly called Purple Fountain Grass, is the showiest of the genus, though all species are quite ornamental in form, texture, and coloring.

They are especially effective in mass plantings or drifts, or as a focal point in decorative containers. Not showing much growth until late spring, they are fine companions for early spring bulbs, filling in and covering the fading foliage of narcissus, crocus, and tulips. They also harmonize well with perennials and shrubs with contrasting leaf texture and flower color such as Rudbeckia, Sedum, Eryngium, Berberis, as well as most conifers and herbs.

The flower racemes of Pennisetums resemble foxtails, range in color from cream to deep purple, and are excellent for use in fresh or dried arrangements. Bloom time typically lasts June through September.
