Producers in temperate grasslands, which have four seasons, include purple needlegrass, buffalo grass, goldenrods and clovers. These plants are identified as producers because they create their own food
Purple needlegrass is a long-lived, tall grass that prevents erosion, controls levees and feeds both cattle and wildlife. Buffalo grass requires little water and grows 3 to 6 inches tall. It develops best in well-drained clay, loam soil or rocky limestone soil. Goldenrod plants are asters. Their yellow blooms show up from late summer through early fall. Purple prairie clover and bush clover are members of the legume family. These plants contribute nitrogen to the soil, a nutrient that is vital for plants.
