Miscanthus Cosmopolitan
Miscanthus sinensis ‘Cosmopolitan’ (Variegated Japanese Silver Grass)Miscanthus Cosmopolitan is a bold ornamental grass prized for its striking variegated foliage and upright growth habit. Its broad green leaves are edged with creamy white margins, creating a dramatic, striped appearance that adds vibrant texture and contrast to the landscape. Growing 4-5 feet tall and 2-4 feet wide, this grass forms commanding clumps that make a strong visual impact in garden designs.
From late summer into fall, Cosmopolitan produces soft, silvery-pink plumes that rise gracefully above the foliage. These blooms mature to silvery-white and persist through winter, providing lasting seasonal interest and movement in the garden. As autumn arrives, its foliage takes on warm golden hues, extending its beauty across multiple seasons.
Highly versatile and low-maintenance, this ornamental grass is well-suited for borders, hedges, or as a dramatic specimen planting. Its drought tolerance, deer resistance, and adaptability to a range of soils make it an excellent choice for both residential gardens and larger landscapes. Whether planted in mass groupings or as a focal point, Cosmopolitan brings year-round interest and structure to outdoor spaces.
Care Instructions:
Planting: Select a site with fertile, well-drained soil. Incorporate organic matter if planting in heavy clay to improve drainage and aeration.
Sunlight: Plant in full sun for the best growth, variegation, and flowering performance. While it tolerates light shade, optimal plume production requires ample sunlight.
Watering: Water regularly during the first growing season to establish a strong root system. Once established, it demonstrates excellent drought tolerance and requires only occasional supplemental watering.
Fertilizing: Feed in early spring with a balanced fertilizer to encourage vigorous foliage and plume development. Avoid over-fertilizing, which can lead to floppy growth.
Pruning: Cut back clumps to 3–4 inches above the ground in late winter or early spring before new growth begins.
Spacing: Allow 3–4 feet between plants to accommodate their mature spread and maintain good air circulation.
Maintenance: Divide clumps every 3–4 years to maintain vigor and manage size. Remove dead or damaged foliage to keep the plant tidy.
