Blue Grama Grass

Blue grama is a compact, warm-season prairie grass with fine blue-green blades and distinctive comb-like seed spikes that curve outward from upright stems. It brings subtle movement and a low, drought-tolerant texture to rock gardens, native meadows, and naturalistic lawn plantings. ## Garden use and appearance The USDA NRCS plant guide describes blue grama as a short perennial, typically 6–24 inches tall, that may grow as a bunchgrass or form low sod depending on region and growing conditions ([USDA NRCS plant guide](https://plants.usda.gov/DocumentLibrary/plantguide/pdf/pg_bogr2.pdf)). North Carolina State Extension notes its blue-gray foliage, summer flower heads, and use in rock gardens, meadows, and low-mow lawn plantings ([NC State Extension](https://plants.ces.ncsu.edu/plants/bouteloua-gracilis/common-name/blue-ramma/)). The Forest Service describes the species as adapted to dry sites and drought tolerant ([USDA Forest Service species review](https://research.fs.usda.gov/feis/species-reviews/bougra)). ## Growing conditions Plant in full sun and well-drained soil. Blue grama tolerates drought and a range of soil textures once established, but it does not thrive in shade or frequently flooded ground. Water new plantings until rooted, then reduce irrigation in climates with suitable summer rainfall. It can be used in small groups among low-growing native plants or as a fine-textured component of a short-grass lawn. ## Seasonal interest The warm-season foliage greens up with rising temperatures, followed by characteristic eyelash-like seed heads in summer. Leaves may take on bronze, orange, or red-brown tones in fall, adding texture after flowering. Its clumps blend well with other prairie grasses and flowering perennials. ## Maintenance Leave the seed heads standing through winter for movement and habitat, then cut the clumps back in late winter before fresh growth. Mow only if maintaining a lawn-like planting, and avoid scalping newly established plants. Remove surrounding weeds while the grass is young, then allow mature clumps to knit together gradually.
