Ornamental grasses add movement, texture, seasonal color, and winter structure, and can serve as edging, focal plants, borders, or screens. Choose by site conditions and purpose: check mature size, light, moisture and drainage, regional hardiness, and whether the plant clumps or spreads. The candidates below are a menu, not a universal ranking; confirm local suitability before planting.
How to Choose Ornamental Grasses
Start with the spot where the grass will grow. Compare mature height and spread with available space, then consider sun or shade, soil moisture, drainage, desired seasonal display, and maintenance. The Missouri Botanical Garden’s ornamental grasses factsheet recommends choosing the right plant for the right place. For regional guidance, consult local extension resources as well as botanical garden references.
Growth habit matters in designed beds. Clump-forming grasses are generally easier to contain; rhizome-forming grasses can spread aggressively. Check local invasive-plant guidance before buying, because behavior and restrictions vary by region.
Ornamental Grass Candidates by Garden Role
This comparison highlights plants and groups supported by the cited garden and extension sources. Dimensions are included only where the research provides them; consult the linked plant guide for additional species-specific details.
#1 Best Overall
- Sow Mar-May or Aug, Oct to the flowering location.
- The soil needs to be finely prepared and well-draining as the variety prefers drier conditions.
- Sow thinly no more than 3-5mm deep. Simply lightly rake over the seed
- Late summer sowing's will produce seed heads the following summer.

Match the Grass to the Site
For upright structure or screening
Consider switchgrass, feather reed grass, big bluestem, Indian grass, and selected little bluestems. Match their mature spread and height to the available bed rather than planting a dense row based on the size of young nursery plants. For ‘Northwind’ and ‘Karl Foerster,’ use the Missouri Botanical Garden dimensions in the table as a starting point.
Rank #2
- Pampas grass is ornamental. Fresh green foliage reaches 8 to 12 feet tall, topped by long, thick silky "featherdusters"
- Pampas ornamental grass grows fairly fast making it an ideal choice for filling in large, barren landscapes
- It will grow in most soils with hardly any work. Low to no maintenance. You can shear ornamental grasses each winter so that new growth comes out clean in Spring
- Cortaderia selloana Pampas Grass has long, graceful blades and fluffy panicles that are beautiful
- Pampas Grass for wind protection and disguising unwanted scenery
For fine texture and edging
Blue grama, prairie dropseed, purple lovegrass, blue fescue, and little bluestem selections offer different forms of fine texture. Compare mature size and site needs for the exact plant or cultivar you are considering; do not assume one selection’s dimensions or color apply to every member of a group.
For shade or part shade
Japanese forest grass, river oats, tufted hairgrass, eastern bottlebrush grass, and selected sedges are options to investigate. University of Minnesota Extension lists these among plants for shady sites, including river oats at 2–3½ feet and Hakone grass at 2–3 feet in its Minnesota guidance. Those recommendations are regional, not a hardiness guarantee for every location.

Shade does not necessarily mean moist soil. Minnesota Extension advises watering shade-site plants well during their first year or two because established trees compete for water. Check soil moisture and drainage before choosing a plant.
For seasonal interest and wildlife value
Little bluestem is noted for seasonal foliage change, while switchgrass and Indian grass provide upright forms and seed heads. Warm-season native grasses can also provide habitat, shelter, food, and structure for wildlife, according to Penn State Extension. Choose cultivar-specific descriptions when foliage color or form is a deciding factor.
Rank #4
- Eragrostis spectabilis is commonly called Purple Love Grass. It is native to the United States both in the east and Midwest. It grows well on sandy infertile soils, and it prefers a location in full sun. Purple Love Grass forms clumps of coarse grass blades. The grass transforms in late summer when the purple colored flowers form.
- Purple love grass grows as a perennial ornamental grass in USDA zones 5 - 10 reaching a height of 20 inches.
- It becomes are haze of rosy purple and dances in the summer breezes making an attractive addition to any landscape. In the fall the foliage turns to a bronze color.
- Uses include naturalizing a landscape or wildlife garden. Purple Love Grass provides cover for ground birds and attracts butterflies. Start the seed indoors 4 – 6 weeks before the end of frost season, or directly sow seed outdoors after frosts have passed
- Sowing Rate: 3 seeds per plant. Press the seed into the soil but do not cover it. Germination is usually in 21 days with temperature ranging from 68 – 72F. This perennial ornamental spreads slowly by rhizomes, and it also will re-seed itself.
Planting and Maintenance
- Check the site: Note sun exposure, soil moisture, drainage, available space, and the plant’s mature size. Check local extension guidance and invasive-plant lists before purchase.
- Plan for growth: Allow room for the mature clump and access for maintenance. Research whether the plant forms a clump or spreads by rhizomes; spreading grasses can become difficult to control.
- Water during establishment: Newly planted grasses need attention as they establish. Shade-site plants may need watering through their first year or two, especially where tree roots compete for water.
- Time cleanup to the plant: Cool-season grasses begin growing earlier in spring; warm-season grasses wait for warmer soil. Many grasses are cut back before new growth, but timing and cut height depend on type and local practice.
- Divide when needed: Division every few years can maintain active growth and address a dead center. Confirm the timing and method for the particular plant.
University of Illinois Extension distinguishes early-starting cool-season grasses from warm-season grasses, which begin growth after soil warms and often offer fall and winter color. Its guidance recommends late-winter or early-spring cutback, with warm-season grasses cut to about four to six inches before new foliage. Check species-specific advice before applying a general schedule.

How do I choose an ornamental grass for a small bed?
Compare the plant’s mature height and spread with the space available, then check light, moisture, drainage, and growth habit. A young plant’s nursery size is not a reliable guide to the space it will need at maturity.
Are ornamental grasses invasive?
Some spreading grasses can become aggressive, particularly rhizome-forming types. Invasive status depends on the plant and location, so check your state or local invasive-plant list and extension guidance before purchasing.
When should ornamental grasses be cut back?
Many grasses are cut back in late winter or early spring before new growth, but timing and cut height vary. Cool-season grasses start earlier than warm-season grasses, so identify the plant and follow species-specific local guidance.
Do ornamental grasses need much watering?
Water newly planted grasses as they establish. Shade-site plants may need watering for their first year or two, since tree roots can compete for moisture. Ongoing needs depend on the plant, soil, and local conditions.
