Sphenopholis obtusata, also known as Prairie Wedge Grass or Prairie Wedge Scale, is a native perennial cool season bunch grass that grows 24″-36″ tall. It prefers full to partial sun, mesic conditions, and soil containing loam, clay-loam, or some rocky material. Most growth and development occur during the spring and early summer. This plant nicely fills in the gaps left between other native grasses and wildflowers.
The foliage is palatable to horses, cattle, and other livestock and is a great choice for a native cool season grass. It can provide stockpile forage for cattle during the fall, winter, and spring.
Sphenopholis obtusata is a host plant for the White-Lined Sphinx Moth. Not much is known about other faunal connections to this plant.
Habitats include mesic prairies, thinly wooded bluffs, open rocky woodlands, and pastures. This species establishes well in recently disturbed areas, which can make it a good competitor in areas with invasive species.
