Windmill Grass:

warm-season, simple perennial grass; bunch-type grass, but spreads with tillers (sideshoots)
has yellow-green, folded leaves, with flattened stem bases; upright to spreading growth habit; grows from 1-10" tall
inflorescence first looks like broom-like digitate panicle, but opens to typical panicle shape; when inflorescences dries, it breaks off from the plant, and tumbles along with the wind (sort of spinning like a windmill ▲)
