What counts as a small ornamental grass
Small ornamental grasses generally stay under about 2 to 3 feet, including flower stems. They suit the front of a border, the edge of a path, gaps between stones and containers. Foliage heights are often much lower than the heights quoted with blooms, so read plant tags closely. For more compact options, see good dwarf grasses for landscaping.
Hameln dwarf fountain grass
Pennisetum alopecuroides ‘Hameln’ is one of the most widely grown compact fountain grasses. Nursery sources typically list it at roughly 18 to 30 inches tall and wide, with flower spikes that may reach about 3 feet, and hardiness around USDA zones 5 to 9.
- Look: arching, fountain-shaped green foliage with soft, bottlebrush plumes from midsummer into fall.
- Fall: foliage often turns golden-tan or copper.
- Light and soil: full sun is best, with well-drained soil. It tolerates dry spells once established but dislikes heavy, constantly wet clay.
- Care: cut back to a few inches above the ground in late winter or early spring, before new growth starts.
- Use: edging, mixed borders and mass plantings.
Some fountain grasses can self-seed in certain areas, so check local guidance if you live somewhere where Pennisetum is a concern. For how fountain grass compares with maiden grass, see Miscanthus vs Pennisetum.
Other small grasses worth a look
- Blue fescue (Festuca glauca): tight blue-gray mounds, typically 10 to 18 inches, for sun and well-drained soil. Often used as an edging along paths. If clumps hollow out, see why blue fescue dies in the center.
- Hakone grass (Hakonechloa macra): a cascading, slow-spreading grass for part shade, with golden or variegated forms and warm fall tones.
- Sedges (Carex): many are evergreen and suit part shade, though some tolerate sun. Selections like ‘Ice Dance’ stay near 12 inches.
- Mondo grass (Ophiopogon): a small, tufted, grass-like plant for shade. Dwarf forms stay just a few inches tall.
- Blue oat grass (Helictotrichon ‘Sapphire’): blue foliage around 2 feet, a good choice for sunny spots and pots.
- Little bluestem: a native clumping grass that offers red and orange fall color; compact selections reach about 2 to 3 feet.
Edging and spacing tips
- Space plants at about their mature width for a continuous edge, or slightly closer for a faster fill.
- Place the smallest plants where they will be seen from the path, and step up in height toward the back. See landscaping with ornamental grasses for layering.
- Use stone or brick edging behind the planting to keep soil and mulch in place.
Can low grasses replace mowing?
Ornamental clumping grasses are not a walkable lawn. They form clumps, not turf, and most do not tolerate regular foot traffic. They can reduce the amount of lawn you mow if used to fill beds or whole areas. Mondo grass and some sedges can form a low, dense groundcover for shade, but they establish slowly. For a fuller plan, see how to replace a lawn with ornamental grasses.
Companions
Pair fine-textured grasses with bolder leaves or flowers, such as coneflower, sedum or hydrangea. See perennials to plant with ornamental grasses. For compact grasses in pots, see growing ornamental grasses in containers, and for shade, see good ornamental grasses that grow in shade.
