Abstract

A new and distinct plant cultivar of little bluestem plant, Schizachyrium scoparium ‘Twilight Zone’ has a dense, upright habit with long arching foliage. Early foliage coloration becomes nearly a silvery mauve-purple by mid-summer that develops brighter purple highlights by early fall. The distal leaves continue up the culm to subtend the rachis in prominent fashion and produce a dense, full, foliar effect. The flowers remain effective with reddish-purple tinting into winter.
