ARKANASAS TURFGRASS: Casey O’Neal, Graduate Research Assistant, Auburn University | Julie Wang, Graduate Research Assistant, University of Georgia | Nikolay Minaev, Graduate Research Assistant, Mississippi State University

Movements such as “Save the Bees”, “No Mow May”, and “Let it Bloom June” are recently trending critiques of monoculture lawns. They highlight the lack of plant and insect diversity in single grass species or cultivar lawns. In recent years, programs like Operation Pollinator have moved the golf industries toward stakeholder interests by supporting research and outreach efforts to improve the ecological function of turf on their facilities. Similarly, the turfgrass industry must prepare to do the same for lawns. While replacing grass lawns with flower gardens, white clover fields, or meadows may be beneficial for pollinators and people in some areas, it ignores the documented want and need for lawns in modern society.

Monoculture lawns, typically a green frame around residential and commercial buildings, accumulate pests and consume a significant sum of inputs. Monoculture lawn alternatives, such as diversified, pollinator friendly, or flower lawns have been discussed; however, a warm-season alternative lawn with known beneficial impact and best management practices (BMPs) has not solidified in science or common practice. Understanding BMPs, and the benefits of these lawns, are crucial goals for the future of the turfgrass industry. The United States Department of Agriculture-National Institute of Food and Agriculture (USDA-NIFA) has funded the Refuge Lawn project to help highlight these goals.

The Refuge Lawn project consists of interdisciplinary researchers from Mississippi State University (MSU), Auburn University (AU), and the University of Georgia (UGA). The team set out to identify low-growing, flowering plants that would be easily established and managed in grass lawns, as well as provide the resources necessary to promote an abundant and diverse pollinator community. As some of the graduate students work on different aspects of the project, we would like to share some of our on-going research.

Picking the right plants

At Mississippi State University, Nikolay Minaev, working with Dr. Jay McCurdy, has been looking for flowering plants that could be easily established and propagated within turfgrasses commonly found in southeastern lawns. After evaluating various species based on their blooming properties and appearances in lawns, it was determined that spring beauty (Claytonia virginica) shows high potential for inclusion in warm-season lawns. Spring beauty is a perennial wildflower that is native to rich forests and low woodlands. It prefers moist, well-drained soil and light shade to part sun. It grows from a small corm or seeds. The growing season lasts from January through April in the temperate climate of the southeast, after which the plant senesces and lies dormant before emerging from corms the next year. The flowers are showy, pinkish white with deep pink veins, and open in clusters at the apex of the plant, adding a burst of color to the lawn during the early spring period. Additionally, it is a resource for pollinators such as the rare spring beauty bee, a small mining bee native to eastern North America.

The current understanding of spring beauty propagation is limited, hence we aim to address this knowledge gap by conducting a comprehensive study. The primary objective is to phenotype different populations of spring beauty and identify those with the most abundant and long-lasting bloom period, accompanied by high seed production and germination rates. This will allow for the selection of the most promising population for inclusion in lawns. In addition to identifying the optimal population, we are also exploring the most convenient method of propagation,
