Grass Category

Ornamental Grass / Ground Cover / Turf Alternative

Hardiness Zones

Thrives in USDA Hardiness Zones 6 through 10. Exhibits good cold tolerance down to roughly -10°F (-23°C) and excellent heat and humidity tolerance.

Grass Family

Asparagaceae, subfamily Nolinoideae (often treated as part of the broader grass-like lily family)

Variety / Cultivar

Variegated or 'Nanus Variegatus', characterized by distinct white or cream-colored stripes along the margins of deep green leaves

About This Grass

Forms dense, fountain-like mounds of arching, grass-like foliage reaching 8 to 12 inches in height. Leaves are dark green with creamy white longitudinal stripes. Small, pale lilac to white bell-shaped flowers appear on hidden spikes, followed by striking blue-to-black fleshy berries.

Blade Characteristics

Medium-coarse texture with leaf widths typically 3-6mm. Blades are linear, flat, slightly leathery, with pointed tips, smooth margins, and distinct longitudinal parallel veins. Vernation is folded, lacking distinct true grass features like membranous ligules and auricles due to its lily family classification.

Root System

Fibrous and dense, featuring thick, fleshy, tuberous roots that help store moisture. Moderate establishment speed, forming a thick, weed-suppressing carpet without aggressive invasive spreading.

Growing Information

Origin Region

Native to warm-temperate and tropical regions of East Asia, including Japan, China, and Korea; widely cultivated globally in temperate to subtropical zones

Growth Habit

Clump-forming (bunch-type) with short stolons and thick, tuberous roots that gradually form dense mounds or mats over time

Sunlight & Water Needs

Performs best in partial shade to full shade, though it tolerates full sun in cooler climates if provided adequate moisture. Moderate water needs once established, prefers moist, well-draining soils rich in organic matter. Good drought tolerance for an ornamental ground cover.

Mowing & Maintenance

Requires little to no mowing; can be occasionally cut back or mowed on a high setting in late winter to remove old foliage and refresh growth. Fertilization is minimal (1 lb N per 1000 sq ft per year or less). Maintenance level is Low.

Special Characteristics

Exceptional shade tolerance, deer and rabbit resistance, good tolerance to foot traffic compared to true grasses, low maintenance, excellent erosion control on slopes, and highly effective at suppressing weeds.

Ecological Information

Introduced ornamental plant with non-invasive tendencies. Provides low-level cover for small ground-dwelling wildlife and beneficial insects. Excellent companion plant for shade gardens, woodland borders, and as a border edging plant.
