Miscanthus sinensis 'Zebrinus': 'Zebrinus' Japanese Silver Grass

Introduction

This cultivar has distinctive yellow strips across the foliage, displaying a variegated effect. Leaves droop and weep toward the ground as do many of the other cultivars. Slender leaves originate in a clump, spreading out and up like a fountain. The 5 to 7 foot tall clumps bear pink flowers in a one-sided inflorescence in late summer and fall that can be used for drying or as a dye plant. Their pinkish or silvery 8 to 10 inch long plumes persist into the winter. Foliage is flexible and blows easily in the wind. This shrub-like grass turns to a rich gold in the fall; the fall color lasts through the winter.

Use and Management

Zebra grass is frequently used in the landscape as a specimen or screen. It is also employed in group plantings, forming a nice mass of fine-textured foliage. Use zebra grass as an accent or mass planted in a large-scale landscape, such as around a commercial building to add a touch of soft elegance and texture. The slightest breeze moves the foliage, allowing the landscape to come alive. Many people prefer to cut the grass back to the ground in the spring so new green growth is not covered with last year's dried, brown foliage.

Zebra grass requires a location in the landscape that receives full sun, but it is adaptable to most well-drained soils. This ornamental grass is quite drought tolerant. Miscanthus sinensis is a warm season grass and transplants best in the spring. Provide good drainage at the planting site.

Other cultivars include 'Condensatus', coarser leaf texture than species, mid-summer bloom, 7 to 8 feet tall; 'Gracillimus', narrower leaves than species, fall bloom, upright growth habit from 5 to 8 feet tall; 'Purpurescens', reddish foliage in summer, purple-red foliage in fall, silver-pink inflorescence, mid-summer bloom, 4 to 5 feet tall; 'Silver Feather', silvery white flowers in August; 'Strictus', horizontal yellow bands on foliage, upright growth habit, 6 to 8 feet tall; and 'Yaku Jima', more compact, 3 to 4 feet tall.

The propagation of Miscanthus sinensis is by division in the spring.

Pests and Diseases

No pests or diseases are of major concern.

Rust disease occasionally infests the foliage, but it often goes away in drier weather.
