Blue Joint Grass is one of the more abundant native grasses on the continent. It blooms in late spring to early summer with pink-green seeds that are attractive but not highly ornamental. Bluejoint refers to the blue-purple color of its nodes. Spreading quickly by shallow rhizomes in moist to wet soils, Blue Joint Grass can help to stabilize stream banks.

The preference is full or partial sun, wet to moist conditions, and cool to warm summer temperatures. This grass adapts to a variety of soil types, including loam, clay, silt, sand, or some combination of the preceding types. It also has a broad pH tolerance. Standing water is tolerated by this grass if it does not persist throughout the growing season. Winter-hardiness is excellent. At some locations, this grass may spread aggressively.
