Purple love grass is a small, perennial, well-behaved ornamental grass in the Poaceae (grass family). This warm-season grass is native to central and eastern North America and is found naturally in sandy fields, along roadsides, and in woodlands. It spreads slowly by rhizomes. Plant purple lovegrass in full sun and well-drained soil. Airy pink seedheads float gracefully above the foliage. It may be used as a lawn alternative and mowed a few times per season; however, Eragrostis will not tolerate heavy foot traffic.
