Smut grass is a warm-season perennial grass that forms dense clumps with narrow leaves and produces distinctive dark, sooty seed heads from summer through fall. This drought-tolerant grass thrives in full sun and poor soils where other plants struggle. It can spread aggressively and may become weedy in some situations.
In an HOA neighborhood
Smut Grass takes more care to keep looking intentional in a front yard. Maintenance level: low. Consider it for backyard or mid-zone beds rather than the street edge.
