Why use native grasses?

  • Bunchgrasses can be used ornamentally as specimens or in groups.
  • Sod forming grasses can make great low maintenance turf and may offer savings in mowing, fertilizing and irrigation.
  • Grasses provide excellent forage and cover for birds and beneficial insects.

Pascopyrum smithii (Agropyron smithii)

Western wheatgrass

12-40”

To 10,500’

Sod-forming grass with upright blue leaves and spikes. Most soils.  Because it is strongly rhizomatous, it should be used only where there is adequate growing space.

Warm Season Grasses Warm season grasses stay dormant longer in the spring, and grow during the warmer season.

Andropogon gerardii

Big bluestem

48-72”

To 7,500’

Robust bunchgrass with upright growth.  Turns red-burgundy in the fall with color retention well into winter. Tolerates most soils (esp. clay) and water regimes.

Andropogon saccharoides

Silver beard grass

24-48”

Bunchgrass with fine textured leaves and large seed heads which catch the light and persist through the winter.  Orange fall color. Grows in all soils, including clay.  Low water use.

Bouteloua curtipendula

Sideoats grama

(Andropogon scoparius)

Little bluestem

Upright growing bunchgrass with green to blue-green leaves and fluffy seed heads that catch the light, persisting through winter.  Fall color is a red to bronze, which fades slowly in winter.  Sun.  Good for clay soils, but tolerates most. Low to moderate water use.
