Blue Grama is easily identified by its distinctive curved "comb-like" seedheads, which appear during the summer. The leaves are light green, drying to a tan color in the winter. In the hot, low deserts, Blue Grama tends to be a small bunchgrass to 2 feet tall by 2 feet wide. In cooler, moist climates it can form a fairly dense sod. It is one of the best grasses for the arid west and can easily be kept at 2" for a xeric lawn.
