Native Wisconsin bluestem grasses offer seasonal garden interest

Native bluestem grasses, specifically little bluestem and big bluestem, offer seasonal color and ecological benefits for Wisconsin landscapes. According to Bruce Spangenberg of the UW-Madison Division of Extension, these Midwestern prairie natives are hardy and provide visual interest through late summer, fall, and winter.

Little bluestem typically grows between 2 to 4 feet tall, featuring blue-green foliage that transitions to red, orange, and purple in autumn. It thrives in full sun and well-drained soil. Big bluestem grows significantly taller, reaching 4 to 8 feet, and is characterized by unique “turkey-foot” shaped flower clusters. Its foliage also turns reddish in the fall, making it suitable for garden screens.

Beyond aesthetics, these grasses support local ecosystems. Their seedheads provide food and shelter for wildlife during winter, while their extensive root systems assist in soil stabilization. The ‘Blackhawks’ cultivar of big bluestem, which features deep purple to black fall foliage, was named the 2026 Perennial Plant of the Year by the Perennial Plant Association.
