Big Bluestem (Andropogon gerardii) Description & Traits
Product Description
Andropogon gerardii (Big Bluestem) is a foundational warm-season prairie grass prized for its bold stature, blue-green summer foliage, and spectacular copper-red fall color. Tall, upright clumps create architectural vertical lines, topped late in the season by the distinctive three-part “turkey-foot” seed heads. Deep roots deliver exceptional drought tolerance and soil stabilization, making Big Bluestem a standout for meadows, restorations, screens, and low-maintenance landscapes.
