Overview
Miscanthus sinensis 'Zebrinus' is a large deciduous clump-forming ornamental grass reaching 6–8 feet (1.8–2.4 m) tall with a spread of 4–6 feet (1.2–1.8 m) and a vase-shaped habit that arches outward and often splays at the base. This is the original banded Miscanthus cultivar and has been in Western horticultural cultivation since the 1870s. Leaves are 0.5–0.8 inches (13–20 mm) wide and carry horizontal golden-yellow bands across the green leaf blades—the cross-banding pattern develops in warm weather beginning in June and is absent from early-season spring growth. Coppery-pink flower plumes emerge in September through October and age to silvery-white through winter. Foliage turns golden-tan in autumn. Growth rate is fast. Hardy to zone 5. The arching lax habit tends to splay outward, particularly after rain events or in rich soil positions. A related cultivar 'Strictus' (porcupine grass) carries the same horizontal banding pattern on a more stiffly upright habit that does not splay.
Native Range
Miscanthus sinensis is native to eastern Asia, ranging across Japan, Korea, China, and Taiwan in open grasslands, meadows, and forest margins. 'Zebrinus' was introduced to Western horticulture from Japanese nursery stock in the 1870s and is the oldest banded Miscanthus in continuous cultivation in Europe and North America. Modern cultivation of ornamental Miscanthus in Western horticulture traces its origin to the Victorian-era introduction of 'Zebrinus' and a small number of related early cultivars.Suggested Uses
Planted as a specimen or screen at 4–6 foot (1.2–1.8 m) spacing in zone-5-and-warmer gardens. Horizontal banding runs visible from mid-summer through autumn and carries the cultivar's primary ornamental character. The arching habit splays outward after rain events and in rich-soil positions—spacing of at least 4–6 feet from adjacent plantings reduces splaying onto neighboring specimens and allows the mature form to extend without crowding. Gardeners wanting the same banded foliage on a more upright habit can substitute 'Strictus'; gardeners working in compact garden positions can substitute 'Gold Bar', which carries the same banding at roughly half the mature size. The cultivar can self-seed in mild climates where M. sinensis escapes garden cultivation. Narrow positions, shade, and regions where M. sinensis is invasive are poor fits for the cultivar.How to Identify

Bloom Information
Coppery-pink flower plumes emerge in September through October and age progressively to silvery-white across the autumn and winter months. Plumes persist through winter on the standing foliage. Active fresh bloom duration is 4–6 weeks.Detailed Descriptions

Care & Maintenance
Care Guide
Full sun in well-drained soil of moderate to lean fertility (pH 5.5–7.5) matches the cultivar's cultivation needs. Hardy to zone 5 (−20°F / −29°C). Full sun positions combined with lean soil help maintain a more-upright habit and reduce the cultivar's tendency to splay at maturity; rich soil and partial-shade positions increase splaying across the growing season. Growth rate runs fast. Drought tolerance develops after first-year establishment. Cutback occurs in late winter. The lax habit on mature clumps may require staking rings or garden-grade cage supports in exposed positions to prevent full collapse after summer rainstorms.Pruning
All stems are cut to 4–6 inches (10–15 cm) above ground level in late February through early March each year. Dried foliage is left standing through winter for structural ornamental interest and cut back only once the coldest weather passes and before new spring growth begins to push from the crown.Pruning Schedule
