Sweet grass has a sweet, long-lasting aroma that is even stronger when the grass has been harvested and dried, and is then moistened or burned. It is burned traditionally during prayer, smudging or purifying ceremonies. The name Hierochloe Odorata is from the Greek, literally "holy fragrant grass".A hardy perennial, sweet grass is harvested by cutting in early to late summer at the desired length. Sweet grass was, and is, used traditionally by North American indigenous peoples. As a sacred plant, it is used in peace and healing rituals. Leaves are dried, made into braids and burned as vanilla-scented incense. Long leaves of sterile shoots are used by Native Americans in weaving.
