Maiden Grass (Miscanthus sinensis): Ornamental Grass Profile

Miscanthus sinensis

Among the showiest ornamental grasses, a clump of maiden grass grows to 7 feet by late summer. The top is wider than the bottom—up to 8 feet wide from a 24-inch base. Stiff, arching leaves extend on all sides. Various cultivars have variegations contrasting with green. Summer leaf beauty is supplanted by magnificent tan-to-red seedheads in late August. Winter brings buff brown leaves and silver seedheads. Frost-covered clumps in front of evergreen hedges are eye-catching.

Planting

Plant in spring to establish before summer heat. Clumps sold in containers. If summer planting, water occasionally. Wait until new blades grow 12 inches before spring division. Tolerates very dry and wet sites. Dig hole 3x container width. No soil amendments needed unless planting in larger island/bed. Spread roots by hand, tamp soil, water thoroughly. Don't plant too deep—standing water causes root rot.

Growing Tips

Fertilize fall-planted clumps late the following spring when leaves grow vigorously. New plants: 1/4 cup 10-10-10 in May, late June, late August. Mature clumps: 1 cup 10-10-10 in May and late August. Except at establishment, watering rarely needed.

Care

By spring, leaves and stems become broken and tattered. Cut all foliage to 6-8 inches. When mature clump center becomes open/hollow, divide. Dig up root ball, plunge sharp shovel through center. Each half can be halved again. Plant one section in original hole, find other spots for the rest.

Companion Planting & Design

Maiden grass' texture is unique—striking accent next to bold plants like black-eyed Susan or purple coneflower. Use as background for perennial border, specimen in lawn, or hedge between properties.

Personal Favorite

Miscanthus sinensis 'Zebrinus' is very striking, with yellow variegation bands crossing the blade every 6 inches from base to tip.
