Big bluestem is a native warm-season grass great for grassland restoration, erosion control, and larger landscaping spaces. This deep-rooted perennial reaches 4-6 feet tall, displaying striking, three-pronged seed heads in hues of green, blue and purple, which makes it useful as a summer "living fence." Drought-tolerant once established, it thrives in full sun and well-drained soils, providing wildlife habitat as well as ornamental interest.
