Low growing ornamental grasses are popular landscape plants because they add texture, movement, and year-round structure without taking up too much space. These compact grasses are suitable for garden borders, pathways, rock gardens, containers, and planting areas where taller plants might overwhelm the design. Their narrow leaves, soft textures, and attractive seed heads can complement flowering perennials, shrubs, and other ornamental plants.
Across the United States and the United Kingdom, small ornamental grasses are used in contemporary gardens, cottage-style landscapes, urban courtyards, and drought-tolerant planting schemes. Some varieties remain evergreen in mild climates, while others produce colourful foliage during the growing season and develop attractive golden or bronze tones in autumn.
Choosing the right low growing decorative grasses depends on several factors, including mature height, sunlight exposure, soil drainage, moisture requirements, and winter hardiness. Some grasses thrive in sunny, dry borders, while others prefer moist soil or partial shade. There are also important differences between true ornamental grasses and grass-like plants, such as sedges and mondo grass, which are often used for similar landscape purposes.
Understanding these differences helps gardeners select plants that suit their available space and local conditions. From compact blue fescue to low-growing Japanese forest grass, many options provide visual interest without requiring the space or maintenance associated with larger ornamental grasses.
What Are Low Growing Ornamental Grasses?
Low growing ornamental grasses are grasses or grass-like plants selected for their compact size, decorative foliage, and contribution to garden design. Many grow between 6 and 18 inches tall, although some varieties remain shorter and others develop taller flower stems above their foliage.
Unlike lawn grasses, which are usually maintained through regular mowing, ornamental grasses are grown for their natural shape, leaf colour, texture, and seasonal appearance.
They may form neat clumps, spreading mats, or flowing mounds of foliage. Some have fine, hair-like leaves, while others feature broader blades with green, blue, gold, or variegated colouring.
Common uses include:
-
Defining garden borders and planting-bed edges.
-
Filling spaces between flowering perennials.
-
Adding texture to rock gardens and gravel landscapes.
-
Creating low-maintenance planting schemes.
-
Softening the edges of paving and pathways.
-
Providing visual contrast in containers and raised beds.
Low growing grasses are particularly useful where a landscape needs structure without blocking views or covering smaller plants. However, gardeners should consider the mature width as well as height, because some compact grasses spread considerably over time.
Best Low Growing Ornamental Grasses for Gardens
Several ornamental grasses and grass-like plants are particularly suitable for small gardens, border planting, and compact landscapes. Their appearance and growing requirements vary, so the best choice depends on the conditions of the planting site.
1. Blue Fescue (Festuca glauca)
Blue fescue is a compact ornamental grass known for its fine, silvery-blue foliage. It forms neat, rounded clumps that usually remain relatively low, making it suitable for sunny borders, rock gardens, and gravel planting schemes.
It prefers full sun and well-drained soil. Excessively wet winter conditions can damage the plant, so good drainage is especially important in areas with heavy rainfall.
2. Japanese Forest Grass (Hakonechloa macra)
Japanese forest grass produces arching foliage that flows gently over the edges of borders and containers. Varieties such as ‘Aureola’ have green and golden striped leaves, creating colour in shaded planting areas.
It generally performs best in partial shade and moist, well-drained soil. It is particularly suitable for woodland-style gardens and sheltered borders.
3. Japanese Sedge (Carex oshimensis)
Japanese sedges, including ‘Evergold’, are popular grass-like plants with narrow, arching leaves. Their green, cream, or golden patterns provide colour in borders throughout much of the year in suitable climates.
They often grow well in partial shade and prefer evenly moist soil with good drainage. Although sedges are not true grasses, they are widely used as small ornamental grass alternatives.
4. Dwarf Mondo Grass (Ophiopogon japonicus ‘Nana’)
Dwarf mondo grass is a very low-growing, grass-like evergreen perennial that forms dense mats of dark green foliage. Its compact habit makes it useful between stepping stones, along pathways, and around the edges of planting beds.
It usually prefers partial shade and well-drained soil. Growth is relatively slow, making it useful where a low, controlled planting is desired.
5. Lilyturf (Liriope muscari)
Lilyturf has arching, strap-like leaves and produces spikes of purple or white flowers, followed by dark berries. It is often used as a border plant beneath trees or along paths.
It tolerates partial shade and can grow in a range of garden soils. Lilyturf is not a true grass, but its foliage makes it a practical option for grass-like planting schemes.
6. Dwarf Fountain Grass (Pennisetum alopecuroides ‘Hameln’)
‘Hameln’ is a compact fountain grass with arching green leaves and soft, brush-like flower plumes. It provides movement and texture during late summer and autumn.
It grows best in sunny locations with reasonably fertile, well-drained soil. Although compact compared with larger fountain grasses, it needs more room than miniature edging plants.
7. Tufted Fescue (Festuca amethystina)
This fine-leaved grass forms compact clumps and produces delicate flower stems above its foliage. Its understated texture works well in naturalistic borders, gravel gardens, and mixed perennial beds.
It generally prefers sunny positions and well-drained soil. As with other fescues, avoiding persistently wet ground helps maintain healthy growth.
Short Ornamental Grasses for Garden Borders
Short ornamental grasses are useful for creating clear edges between lawns, pathways, and flower beds. Their compact growth helps define planting areas without obscuring flowers or obstructing views.
Blue fescue is particularly effective in sunny borders because its rounded shape and blue-grey foliage contrast with green-leaved perennials. Dwarf mondo grass works well in narrower spaces where a very low, uniform appearance is needed.
Japanese sedge can provide a softer border in partially shaded areas, while Japanese forest grass adds a flowing shape around steps, retaining walls, and the edges of raised beds.
When choosing border grass plants, consider the width of each mature clump. A plant that appears small in a nursery pot may spread significantly as it establishes. Spacing plants according to their expected mature width reduces overcrowding and limits the need for frequent division.
For a naturalistic appearance, grasses can be mixed with low-growing flowering plants such as creeping thyme, hardy geraniums, and compact salvias, provided the plants share similar light and moisture requirements.
Small Ornamental Grasses for Sun and Shade
Light exposure is one of the most important factors when selecting small ornamental grasses. A variety that thrives in full sun may become weak or lose its colour in a shaded location.
Grasses for Sunny Gardens
Blue fescue and other compact fescues generally perform well in full sun. Their fine foliage works particularly well in gravel gardens, rockeries, and drought-tolerant borders once plants are established.
Compact fountain grasses are another option for sunny spaces, although they usually require more room and moisture than blue fescue.
Sunny sites tend to dry out faster, so soil drainage and watering during establishment should be considered carefully.
Grasses for Shaded Gardens
Japanese forest grass is a suitable choice for partial shade, where its arching foliage can brighten planting areas beneath trees or beside buildings.
Japanese sedges and dwarf mondo grass are also useful in shaded borders. They can provide foliage texture where flowering plants may struggle with limited sunlight.
However, dense shade and dry tree-root competition can limit growth even for shade-tolerant plants. Checking soil moisture and the amount of available light helps determine whether a planting location is suitable.
Small Oriental Grass and Compact Miscanthus Varieties
The phrase small oriental grass is sometimes used when searching for compact ornamental grasses associated with East Asian garden styles. It may refer to Japanese forest grass or smaller varieties of maiden grass, depending on the context.
Maiden grass belongs to the genus Miscanthus. Many varieties grow quite tall, but selected dwarf cultivars are more suitable for smaller planting spaces.
For example, compact forms such as Miscanthus sinensis ‘Little Kitten’ can provide the fine foliage and upright flower stems associated with larger maiden grasses without reaching the same size as vigorous cultivars.
However, even compact Miscanthus varieties can be taller than typical edging grasses. Their mature height and width should be checked before planting, particularly in small courtyards or narrow borders.
Gardeners should also consider local environmental guidance before planting ornamental grasses. Some Miscanthus species or cultivars may self-seed or spread in certain conditions, so selecting a suitable, well-behaved cultivar is important.
How to Grow and Maintain Small Ornamental Grass Plants
Most small ornamental grasses are relatively easy to maintain once established. However, their long-term health depends on choosing suitable soil, light exposure, and watering conditions.
Soil and Drainage
Many compact ornamental grasses prefer well-drained soil, particularly blue fescue and other plants adapted to sunny, dry conditions. Soil that remains saturated for long periods can damage roots and encourage fungal problems.
Other plants, such as Japanese forest grass and many sedges, prefer more consistent moisture. Improving soil with suitable organic matter can help, but the type and amount should reflect the plant’s needs.
Watering Requirements
Newly planted ornamental grasses need regular watering while their roots establish. After establishment, watering requirements vary by species.
Blue fescue generally tolerates some dryness, while Japanese forest grass usually performs better when the soil does not dry out completely for extended periods.
Container-grown plants often need more frequent watering than those planted directly in the ground because pots lose moisture more quickly.
Pruning and Seasonal Care
Most deciduous ornamental grasses can be cut back in late winter or early spring before new growth begins. This removes old foliage and allows fresh leaves to develop.
Evergreen grasses and grass-like plants usually need lighter maintenance. Remove dead or damaged leaves as necessary rather than cutting the entire plant back indiscriminately.
Some clump-forming grasses can be divided when they become congested or develop a dead centre. Division is generally carried out during a suitable growing period, depending on the species and local climate.
Winter Hardiness
Winter conditions differ significantly across the USA and UK. A grass that remains evergreen in a mild British coastal garden may lose foliage or suffer damage in a colder inland location.
Check the hardiness and winter moisture requirements of the selected variety. In areas with cold, wet winters, good drainage is especially important for plants such as blue fescue.
Benefits of Low Growing Decorative Grasses
Low growing decorative grasses provide several practical and visual benefits in landscape design.
-
Compact growth: They fit into narrow borders, small courtyards, and planting areas with limited space.
-
Texture and movement: Fine leaves and flower stems add contrast to broader-leaved plants.
-
Seasonal interest: Many varieties change colour or develop attractive seed heads during autumn.
-
Versatile planting: They can be combined with perennials, shrubs, bulbs, and ground-cover plants.
-
Reduced mowing: Ornamental grasses are grown for their natural appearance and generally do not require lawn-style mowing.
-
Wildlife value: Some grasses provide seeds or shelter for wildlife, although their ecological benefits depend on the species and planting location.
These advantages make compact grasses useful in both traditional and contemporary gardens. Nevertheless, not every ornamental grass is drought-tolerant or low-maintenance, so selection remains important.
