A native prairie grass with deep Texas roots

Sideoats grama (Bouteloua curtipendula) isn’t just a tough native grass—it’s the official state grass of Texas. Found throughout the state and across much of North America, this warm-season perennial is a foundational species in prairies and grasslands. With its distinctive seed spikes and remarkable drought tolerance, sideoats grama plays a vital role in native landscapes, soil health, and habitat restoration.

What Does Sideoats Grama Look Like?

Sideoats grama grows in clumps, typically reaching 1 to 2.5 feet tall. Its most recognizable feature is the row of oat-like spikelets that dangle from one side of the stem—hence the name “sideoats.” These flowering structures often have a purplish tint during bloom, giving the grass a unique visual appeal.

• Growth form: Bunchgrass with narrow, gray-green leaves

• Flowering time: Generally, from late spring through summer

• Seed spikes: Arranged on one side of the flowering stem, often reddish or purplish at anthesis

• Root system: Deep and fibrous, helping with erosion control and drought survival

Native Habitat and Distribution

Sideoats grama is native to Texas and much of the U.S., thriving in dry prairies, rocky slopes, and open woodlands. It is especially well adapted to central and western Texas, where high heat, drought, and poor soils challenge less hardy species.

• Hardiness: Zones 4–9

• Soil preference: Well-drained, calcareous, or sandy soils

• Sunlight: Prefers full sun and does not compete well in shaded conditions

Its natural range extends from Canada to Argentina, making it one of the most widely distributed native grasses in the Western Hemisphere.

Ecological Importance

As a native species, sideoats grama plays a crucial role in supporting local ecosystems:

• Erosion control: Its dense root system helps stabilize soil on slopes and disturbed sites.

• Wildlife habitat: Provides forage for livestock and habitat for pollinators, including native bees and butterflies.

• Resilience: Withstands drought, fire, and grazing pressure—making it a key species in prairie restoration and conservation efforts.

It is especially valuable in regions like Houston and Central Texas, where landowners and land managers are increasingly turning to native plants for low-maintenance, sustainable landscapes.

Uses in Landscaping and Restoration

Sideoats grama is used extensively in native landscaping, erosion control, and prairie restoration projects. Because it grows well in poor soils and with minimal irrigation, it’s an ideal choice for:

• Roadside plantings

• Urban wildflower meadows

• Native grass mixes

• Habitat restoration sites

In managed landscapes, it pairs well with other Texas natives like little bluestem, switchgrass, and native wildflowers.

A Symbol of Texas Heritage

Designated the official state grass of Texas in 1971, sideoats grama symbolizes the state’s connection to its native prairie heritage. Its resilience, beauty, and ecological importance make it a fitting emblem for Texas landscapes.
