Miscanthus sinensis Cosmopolitan

Cosmopolitan Maiden Grass

Miscanthus sinensis ‘Cosmopolitan’ is a bold, warm-season ornamental grass valued for its large size and striking variegated foliage. Broad green leaves with creamy-white margins emerge in spring, arch gracefully through summer, and take on golden tones in fall, followed by showy plumes in late summer that emerge pinkish and mature to silvery-white, persisting into winter for added interest. Its tall, arching habit makes it a strong focal point in the landscape.
