Pennisetum Rubrum
‘Rubrum’, sometimes commonly called purple or red fountain grass, is a burgundy-red leaved cultivar that is not invasive under any circumstances because, unlike the species, it rarely sets seed. Showy, fluffy, burgundy-purple flowers in bottlebrush-like spikes (to 12” long) top flower stalks that arch upward and outward above the burgundy-red foliage clump in summer.
