Wisconsin Native Grasses and Sedges

12 native grasses that are proven winners and will add interest and color to your yard.

  Our Native Prairies

Native grasses formed the foundation of the expanses of prairies, savannas and meadows that once covered the greater mid-west. They are a natural component, or the basis, of any designed native landscape — offering the perfect complement to native wildflowers in both naturalized and formal settings.

  Deep Roots

Native plants have deep roots that help hold the soil in place and greatly improve the soil's ability to absorb and filter water, removing pollutants before they enter our rivers and streams. During the dry summer months, native root systems reach deep into the ground to find water, making them more drought resistant than non-native grasses.

Prairies with their native grasses are sometimes called upside-down forests because much of the plant is below the ground. Many native grasses have roots 5 to 15 feet deep. Typical lawn grasses reach a depth of only a few inches.

  Grasses Versus Sedges

Sedges are primarily perennials, and are mostly evergreen, cool-season, shade-loving plants. They generally prefer moist to wet environments. While more diminutive than many grasses, sedges provide support to a variety of animals. Native sedges belong to the genus Carex, at around 2,000 species, one of the largest plant genera on earth.

The stems of grasses are hollow and either round or flat with swollen nodes or joints along the stems. Their leaf blades are flat and their leaf sheaths are open. The stems of sedges, on the other hand, are generally solid and triangular. Their leaf blades may be folded, and the base of each leaf is closed around the stem.

  Cool Season Or Warm Season Grasses

Grasses that mature early in the growing season and grow while the soil is still cool are referred to as “cool season” grasses. Virginia Wild Rye and Tufted Hairgrass are cool season grasses. Sedges are also cool season growers. Indian Grass, Little Bluestem, Big Bluestem and Prairie Dropseed are all warm season grasses.

Big Bluestem Benefits: Birds Height: 5-8 feet Bloom: Aug, Sep, Oct Sun: Full Sun Zones: 3-8 Soil: Clay, Loam, Sand Moisture: Dry, Medium, Moist	Description: Big Bluestem (Andropogon gerardii) is a tall perennial, warm season grass that was the dominant grass of the tallgrass prairie. It may be grown as an ornamental grass because of its attractive foliage which changes color seasonally, its good architectural height and its interesting flower/seed heads.
Buffalograss Benefits: None Height: 3-9 inches Bloom: Jun, Jul, Aug Sun: Full Sun Zones: 4-8 Soil: Acid, Clay, Loam Moisture: Dry, Medium	Description: Buffalograss, Buchloe dactyloides, is a dioecious, drought-tolerant, heat-resistant, fine-textured, warm season perennial grass. It spreads by stolons. Somewhat inconspicuous green flowers bloom from June until August. Easily grown in average, dry to medium moisture, well-drained soil in full sun.
Sideoats Grama Benefits: None Height: 2-3 feet Bloom: Aug, Sep Sun: Full Sun Zones: 3-9 Soil: Sand, Loam Moisture: Dry, Medium	Description: Side-oats Grama (Bouteloua curtipendula), is a rarity among native grasses in that it sports tiny attractive flowers during its summer bloom time. When the seed heads dry, they have a distinctly oat-like appearance. Side-oats is a warm-season grass that grows actively during the summer months when soil temperatures are warm. May be mowed for turf grass.
Virginia Wild Rye Benefits: Butterflies Height: 4-5 feet Bloom: Jul, Aug Sun: Full Sun, Part Sun, Part Shade Zones: 2-8 Soil: Clay, Loam, Sand Moisture: Medium, Moist, Wet	Description: Virginia Wild Rye (Elymus virginicus) is a graceful, short-lived perennial similar to Canada Wild Rye, but with a smaller, less showy seed head. It actively grows during the spring and fall when soil temperatures are cool. As a fast-growing grass, Virginia Wild Rye is a good choice for erosion control and stream bank stabilization. It prefers rich, moist areas in clearings or along the forest edge, but can also grow in drier, sunny conditions as well.
Indian Grass Benefits: Butterflies Height: 5-8 feet Bloom: Aug, Sep Sun: Full Sun Zones: 3-9 Soil: Clay, Loam, Sand Moisture: Dry, Medium, Moist	Description: Indian Grass (Sorghastrum nutans) is a warm season perennial grass which typically occurs in prairies, glades and open woods. It was one of the dominant grasses of the tallgrass prairie which once covered large parts of the Midwest. It forms upright clumps of slender, blue-green leaves Foliage turns orange-yellow in fall and usually retains hints of color into the winter. Effective for erosion control
Little Bluestem Benefits: N/A Height: 2-4 feet Bloom: Aug to Feb Sun: Full Sun Zones: 3-10 Soil: Loam Moisture: Dry, Medium	Description: Little Bluestem (Schizachyrium scoparium), a native to prairies, fields, clearings, hills, limestone glades, roadsides, waste areas and open woods. It was one of the dominant grasses of the vast tallgrass prairie region which once covered rich and fertile soils. Purplish-bronze flowers on branched stems rising above the foliage in August. Flowers are followed by clusters of fluffy, silvery-white seed heads which are attractive and often persist into winter.
Fox Sedge Benefits: None Height: 1-3 feet Bloom: May, Jun, Jul Sun: Full Sun, Part Sun Zones: 3-9 Soil: Loam Moisture: Wet	Description: Fox Sedge (Carex vulpinoidea) is a remarkable wetland sedge grows to form clumps two feet in diameter. In mid-summer seed heads spray out from the center of the plant for an excellent effect. Its narrow grass-like leaf blades grow in 2 feet clumps up to 3 feet in height. The seed heads, which spray out attractively from the center of the clump, resemble a fox's tail but are short-lived.
Pennsylvania Sedge Benefits: None Height: 6-12 inches Bloom: May Sun: Part Shade, Shade Zones: 3-9 Soil: Loam Moisture: Dry, Medium	Description: Pennsylvania Sedge (Carex pensylvanica) is a shade-loving perennial sedge that is native to thickets and dry woodland areas. It typically grows in loose colonies with a creeping habit. Roots are reddish brown. It is often found in areas with oak trees, hence the additional common name of oak sedge. This is a low sedge with soft, delicate, arching, semi-evergreen leaves. It typically grows in a clump. It is semi-evergreen in moderately cold winter climates.
Pink Muhly Grass Benefits: Birds Height: 2-3 feet Bloom: Sep, Oct Sun: Full Sun, Part Sun, Part Shade Zones: 5-11 Soil: Clay, Loam, Sand, Rocky Moisture: Dry, Medium	Description: Pink Muhly Grass (Muhlenbergia capillaris) is one of the most exciting members of the grass world.
