South Dakota is home to several native prairie clovers that provide important benefits for pollinators, wildlife, livestock, and natural landscapes. These attractive plants add color and diversity to prairies while helping support healthy ecosystems across the state.
Sara Ogan, SDSU Extension Horticulture Assistant, along with Allison Dollen, SDSU Extension Native Plant Field Specialist, and Robin Buterbaugh, highlighted that prairie clovers are native members of the legume family rather than true clovers. These plants develop deep taproots, produce fragrant flowers, improve soil fertility by fixing nitrogen, and provide valuable forage for livestock. Their nectar supports native bees and butterflies, while birds and other wildlife feed on their seeds.
Prairie clovers belong to the Dalea genus, named after English botanist Samuel Dale. Each species has unique characteristics, preferred growing conditions, and even distinct fragrances. Some species may have scents similar to pine, lemons, or oranges when their leaves are gently rubbed.
Purple prairie clover (Dalea purpurea) is one of the most recognized species in South Dakota. Its bright purple flowers grow on cone-shaped flower heads and attract many pollinators. The plant performs well in sunny locations with average to dry soils and is often used in naturalized landscapes.
White prairie clover (Dalea candida) blooms during June and July and produces white flowers. It grows well in dry to moderate prairie conditions and adapts to many well-drained soils. This species is commonly planted in prairie and meadow gardens.
Silky prairie clover (Dalea villosa) produces light purple flowers during July and August. Its stems and leaves are covered with fine hairs, helping distinguish it from similar plants. This drought-tolerant species grows best in sandy soils and prairie environments.
Golden prairie clover (Dalea aurea) features bright yellow flowers and thrives in rocky slopes, hillsides, and dry locations. Its ability to tolerate heat and drought makes it a valuable addition to rock gardens.
Foxtail prairie clover (Dalea leporine) is an annual species that can be reseed naturally under suitable conditions. It grows in sunny areas with sandy or disturbed soils and requires little maintenance once established.
With species suited to many soil and moisture conditions, prairie clovers offer attractive and practical options for supporting pollinators, wildlife, and healthy landscapes throughout South Dakota.
