Native Ornamental Grasses in Oklahoma

Native grasses and sedges that bring movement, winter structure, and bird seed — the matrix that ties a planting together. Oklahoma sits in a landscape of Cross Timbers & mixedgrass prairie, and the natives that thrive here are the ones built for its continental, hot summers character. The list below — led by Pink Muhly Grass and Sideoats Grama — is filtered to species genuinely native to Oklahoma and the wider flora of the Great Plains and hardy through zones 6–8. Native grasses are the connective tissue of a natural planting, weaving between the flowers, holding the soil, and standing handsome through the whole winter. Warm-season grasses want full sun and lean soil and green up late, so don't give up on them in May. Cut everything back to a hand's height in late winter, just before new growth, and that's the entire job.
