Purple Fountain Grass: Division, Seeds, and Overwintering in Zone 7b

Purple fountain grass is a warm-season hybrid often sold as an annual. It divides easily—most cultivars are propagated this way because seeds are often sterile. In Zone 7b (NC), it will not overwinter outdoors. Indoor overwintering is rarely successful; best to buy new plants each spring or divide in spring.

If attempting seeds, let plumes dry on the plant, collect when fully brown, but expect variable results. High-nitrogen fertilizer encourages more plumes and seeds, but division remains the reliable method.
