Blue Grama Grass (Bouteloua gracilis) is a long-lived, clump-forming, warm-season, perennial grass native to North America. It is one of the dominant grasses of the dry shortgrass prairies. Blue grama has very thin green to greyish leaves that turn golden brown in autumn, sometimes also developing interesting shades of orange. Purplish-tinged eyebrow-shaped flowers appear on arching stems above the foliage in early to mid-summer. Height before flowering is 12-15" increasing to 24" after flowering. As a native to the Great Plains, blue grama displays excellent drought tolerance but tolerates a wide range of soils. Avoid poorly-drained soils. In Eastern Kansas, typically our 40 inches of rainfall is sufficient without extra water. Occasionally suffering from excessive rainy spells and high humidity, foliage rust diseases can be a problem in shade or poor air circulation areas. To counteract that in Kansas, plant in full sun on berm with poor sandy, rocky, or clay soil with no irrigation. Blue grama grass works very well in an ornamental grass garden adding contrast, texture, and short stature. Use as mass plantings to create a drift that can be enjoyed from far away. For mass plantings, plant individual plants close together as they don't spread much. Dried foliage holds up very well in the winter offering a one-of-a-kind look. The only maintenance is to cut down or burn before new growth emerges. Combine with other flowering prairie native perennials for a long season of interest. Also useful as a full-sun turf grass for extremely dry or sandy soils or where buffalo grass doesn't work. It can be regularly mowed to 3-4" high.
