Wilman Lovegrass (Eragrostis superba) is a warm-season perennial bunchgrass native to South Africa. It has spread to regions like the United States and Argentina, valued for its robust nature in land management and agriculture.
Key Characteristics of Wilman Lovegrass
Wilman Lovegrass grows as a tall, erect bunchgrass, forming tight, upright clumps typically 2 to 5 feet tall. It features numerous slender leaves, approximately 12 to 18 inches long, emerging from its base. Distinct seed heads measure 8 to 10 inches long. The grass possesses a vigorous root network, contributing to its resilience and ability to access water.
Primary Uses of Wilman Lovegrass
Wilman Lovegrass serves multiple purposes. It is widely utilized as palatable forage and hay for livestock due to its good digestibility. The grass is effective in erosion control, as its robust root system stabilizes soil and prevents loss from wind or water. It is also planted in rangeland mixtures for rapid cover. Additionally, its dense foliage provides cover and nesting sites for wildlife, and its seeds are a food source for some bird species.
Establishment and Cultivation
Successful establishment of Wilman Lovegrass requires proper timing and site selection. The optimal planting period is spring, from February to June, encouraging robust growth. This grass needs a sunny location, receiving at least six hours of direct sunlight daily, and thrives in well-drained soils. It adapts to a wide range of soil types, including sandy and sandy loam, and tolerates pH levels from 4.5 to 8.0.
Before planting, prepare a firm, clean-tilled seedbed to improve germination. Drilling is effective, but broadcasting followed by rolling also works for good seed-to-soil contact. Seeds should be planted at a shallow depth, typically 1/4 inch, as most grass seedlings cannot emerge through deeper soil. Initial watering is important for germination and early growth, ensuring consistent moisture without overwatering until the grass is established.
Ongoing Management
Once established, Wilman Lovegrass exhibits moderate drought tolerance, though consistent moisture levels promote optimal vigor. During dry spells, it can withstand water scarcity but may brown out or go dormant until moisture returns. Established plants benefit from thorough watering when the soil is dry, allowing water to saturate the root zone. While generally robust and low-maintenance, periodic trimming can help maintain its shape and encourage fresh growth, and pruning in early spring or winter can invigorate the plant.
Fertilization is not always necessary, as it tolerates low fertility soils, but it performs best on fertile ground. Grazing management is important; while palatable, continuous or overly close grazing can lead to a decline in stand persistence if the grass is not allowed to periodically produce seed. Wilman Lovegrass is resistant to many common pests and diseases, contributing to its ease of care.
Advantages and Disadvantages
Wilman Lovegrass offers several advantages. It establishes easily and grows quickly, providing rapid ground cover. Its strong drought tolerance allows it to thrive in arid and semi-arid regions, adapting well to a wide variety of soil types, particularly sandy and sandy loam soils. The grass is effective for erosion control and soil stabilization due to its extensive root system. Additionally, it is palatable for livestock and provides habitat and food for wildlife.
However, there are considerations when choosing Wilman Lovegrass. It lacks strong cold tolerance, which can limit its adaptation in colder climates. While often less invasive than some other introduced grasses, it can spread from planted areas, potentially impacting native plant diversity, especially in very sandy soils. Its palatability means it can decline if grazed too closely and persistently without allowing for seed production.
