Weeping Lovegrass, known botanically as Eragrostis curvula, is a warm-season bunchgrass introduced initially to the United States from East Africa. It was brought over primarily for erosion control and forage purposes, thanks to its rapid growth and ability to thrive in poor soil conditions. The grass gets its name from its long, pendulous leaves that droop downward, creating a graceful, weeping appearance.
Historically, Eragrostis curvula was introduced to the U.S. for its ability to stabilize soil, particularly in areas prone to erosion. It has been widely planted on disturbed lands, including mine spoils and steep slopes, where it quickly establishes itself and provides ground cover. Over time, it has naturalized in various regions, particularly in the southern United States.
This grass prefers well-drained, light-textured soils and can tolerate low fertility conditions. It is highly adaptable to different climates, although harsh winters can limit its regrowth, causing it to behave as an annual or short-lived perennial in colder regions. The plant produces open panicles with numerous small seeds, which contribute to its efficient spread.
Essential cultural practices for growing and maintaining Weeping Lovegrass:
- Plant in well-drained, sandy or loamy soils
- Sow seeds at a rate of 3 to 5 pounds per acre for pure stands or 1 to 2 pounds per acre in mixtures
- Ensure seeds are not buried deeper than 1/2 to 1 inch in sandy soils or 1/4 inch in silt loams
- Use mechanical seeders with small seed attachments or mix seeds with a carrier for even distribution
- Lime and fertilize similarly to tall fescue or ryegrass when used for temporary cover
- Establish after the danger of severe frost has passed, with planting possible throughout the summer
- Provide occasional mowing or grazing to maintain plant health and prevent excessive self-seeding
Weeping Lovegrass is valued for its ability to prevent soil erosion, provide forage for livestock, and support wildlife by offering seeds for birds and small mammals. However, in some regions, it has been classified as invasive due to its aggressive growth and tendency to spread beyond intended planting areas.
