Oryzopsis asperifolia
Rough-leaved ricegrass Description:
Oryzopsis asperifolia, commonly known as roughleaf ricegrass, is a native perennial grass species that is commonly found in the western region of North America, particularly in the Great Basin and Rocky Mountains. The plant grows in clumps and can reach up to 10-26 inches in height.
The leaves of Oryzopsis asperifolia are rough, narrow, and can be up to 10 inches long. The plant produces spikelets, which are small flowers, that grow in clusters along the stem. The flowers bloom from early summer to early fall and are followed by seeds that can be dispersed by wind or animals.
Oryzopsis asperifolia is a drought-tolerant species that can thrive in a variety of soil types and conditions, including rocky, dry, and alkaline soils. It is often used in landscaping as an ornamental grass due to its attractive appearance and hardiness. Additionally, the plant is an important forage source for wildlife, such as deer and elk, and provides valuable habitat for many bird species.
Native Range:
Rough-leaved ricegrass is found in most parts of Minnesota, with the exception of Southwestern portions of the state. More broadly, it can be found across the Northern parts of the United States with an additional Southern range extending from Montana to New Mexico.
Standard Plant Information:
Plant height: 10" - 26" inches
Fruiting time: May - July
Preferred habitat: Does well in part shade to sun and average to dry rocky soil. Often found in open hardwood and mixed forests, jack pine stands, and clearings.
Sowing:
For most homeowners, the best option is to scatter seed on the ground by hand broadcasting at a minimum of 15-16 pls lbs per acre. For even coverage, we recommend that you broadcast seed in perpendicular rows across the site to ensure even coverage.
Planting:
Simply dig a hole in the soil slightly larger than the plant’s roots. Ensure that the soil line of the plant is maintained during the transfer (i.e. the plant should be at the same level with the ground as it was in the pot). Pack any loose dirt back around the plant and make sure you water it well the same day to ensure it has the best chance of survival.
