Korean velvet grass

Zoysia tenuifolia
Korean velvet grass (Zoysia tenuifolia) is an extremely fine-textured, warm-season turfgrass native to East Asia, prized as a low, almost mossy 'no-mow' lawn alternative and groundcover. Left unmown it knits into a dense, undulating carpet of tiny needle-fine blades that mounds and ripples like green velvet - the look that earns its other names, 'temple grass' and 'Mascarene grass.' It is slow to establish but, once knit in, dense and surprisingly traffic-tolerant. Two honest caveats keep it from being a carefree choice: it spreads aggressively by surface stolons (runners) and will creep into beds and over a neighbor's edge unless contained by hard edging, and like all zoysias it is a warm-season grass that turns straw-brown and goes dormant through cool weather - it is NOT evergreen in winter. Its taxonomy is also muddled: many authorities treat Zoysia tenuifolia as a synonym of Zoysia matrella or Zoysia pacifica, so it travels under several names in the trade.

River oats (Chasmanthium latifolium) as a whole green-season clump in a rock garden, showing the broad bamboo-like blades and arching stems hung with flat oat-like spikelets.
Chasmanthium latifolium
River oats
A native cool-to-warm-season grass forming graceful upright clumps with distinctive flat oat-like seed heads that dangle decoratively from the stems through summer + fall. Often called sea oats (though true sea oats are Uniola paniculata, a coastal species). Among the few native grasses that tolerates significant shade - useful for woodland-edge plantings. Self-seeds vigorously in moist soils; manage seedheads in formal settings.

Bearberry (kinnikinnick)
A circumboreal evergreen groundcover with small white-pink urn-shaped flowers, glossy leathery leaves, and bright-red bear-edible berries. One of the most reliable native evergreen groundcovers for cold sandy sites; widely used in northern landscapes for slope stabilization + low-maintenance native plantings.

Bergenia cordifolia clump showing large, heart-shaped, leathery dark-green leaves with red-flushed margins at Merrifield Garden Center, Virginia
Bergenia cordifolia
Elephant's ears
Bergenia cordifolia (often treated by botanists as a synonym within B. crassifolia) is a tough, evergreen perennial native to the Altai Mountains, southern Siberia and Mongolia, grown for its bold, heart-shaped leathery leaves that flush red-bronze through winter and its deep pink flower spikes in early-to-mid spring. It is one of the most tolerant groundcovers in cultivation - enduring deep shade, poor soil, drought, and hard continental cold (commonly rated to USDA Zone 3 in US horticulture; RHS rates it H7, hardy below -4°F). The honest catch is its shallowly creeping rhizomes: in mild, moist climates they can colonise well beyond the intended planting, and the large, persistent leaves trap fallen debris and are notoriously attractive to slugs and vine weevils.

Liriope muscari clumps with lilac flower spikes growing as groundcover in the Institute for Nature Study, Tokyo
Liriope muscari
Lilyturf
Liriope muscari is an evergreen, grass-like perennial native to the shady forest understories of China, Japan, and Korea, where it grows at elevations of 330 to 4,600 feet. In gardens it forms dense, weed-suppressing clumps of arching dark-green foliage topped by spikes of lilac-purple flowers in late summer, followed by ornamental black berries - earning it the RHS Award of Garden Merit. It is drought-tolerant and remarkably adaptable, but the honest catch is its behaviour outside its native range: in parts of the eastern United States it is a documented invasive species, spreading by rhizomes and self-seeding into natural areas, and it provides minimal wildlife value compared with native groundcover alternatives.

Cotoneaster horizontalis showing herringbone branching laden with red berries in late autumn at the Berlin-Dahlem Botanical Garden
Cotoneaster horizontalis
Creeping Cotoneaster
Creeping cotoneaster is a deciduous spreading shrub native to the mountains of central and southwestern China, Nepal, and Taiwan, prized for its distinctive flat herringbone branching, tiny pink-white summer flowers, and masses of vivid red autumn berries that sustain birds through winter. It holds the RHS Award of Garden Merit and tolerates poor, dry soils on banks and walls where little else will perform. The honest catch is twofold: the berries are mildly toxic to humans and pets (cyanogenic seeds, GI-irritant flesh), and the plant self-seeds freely enough that it is naturalising widely in the UK and Ireland and is considered potentially invasive - a real concern before planting near wild margins or hedgerows.

Common oat (Avena sativa) - nodding oat spikelets in an open panicle, slender drooping pedicels, flat blue-green grass blades, erect cereal-grass habit.
Avena sativa
Common oat
The cultivated cereal oat, an erect cool-season annual grass grown for grain, forage, and - increasingly in gardens - as a fast, soil-building cover crop. From a spring or late-summer sowing it shoots up to 2 to 4 feet of slender, upright culms topped by an open, airy seed head (a spreading panicle) whose dangling spikelets ripen from green to gold. Domesticated in the Old World from wild oats, it is not a native wildflower but a true annual crop: it germinates fast, smothers weeds, builds biomass, and in cold zones conveniently winter-kills to leave an easy mulch in spring. Gardeners reach for it most as a green manure and erosion-stopping nurse crop, and for the soft, grassy texture and ripening-gold seed heads it adds while it grows.
