Also called holygrass or bisongrass, sweetgrass is a native prairie grass prized for its fresh scent. It grows naturally in meadows and along stream banks. Native American tribes have long used sweetgrass for making smudge sticks as well as for weaving baskets. The plant spreads up to 2 feet wide annually, so plant it where it can be confined. It eventually forms a thick mat of foliage that tends to flop over unless cut back.
