Description
Andropogon ternarius ‘Black Mountain,’ commonly known as Big Bluestem, is a striking ornamental grass prized for its dramatic deep burgundy to nearly black foliage that intensifies in color as the season progresses. Native to eastern North America, Big Bluestem is a warm-season perennial grass that can reach heights of 4 to 7 feet, featuring slender, upright stems topped with airy, purplish flower panicles in late summer. This cultivar’s unique dark foliage provides bold architectural interest and serves as a dynamic contrast in mixed borders, prairie-style gardens, and naturalistic landscapes. Renowned for its drought tolerance, adaptability to various soil types, and ability to attract wildlife such as birds and pollinators, ‘Black Mountain’ offers both aesthetic appeal and ecological benefits. The species historically played a crucial role in prairie ecosystems and was valued by Native American cultures for its utilitarian uses. This cultivar has gained recognition within the gardening community for its ornamental value, contributing to the resurgence of native grasses in sustainable and low-maintenance landscape designs.
