Native Groundcover Plants in South Dakota

Low, spreading natives that knit together to cover bare ground, smother weeds, and replace thirsty lawn or mulch. Every species here is genuinely native to South Dakota and the wider flora of the Great Plains and hardy through zones 3–5 — proven performers for South Dakota's continental, semi-arid climate across Black Hills & mixedgrass prairie, not a generic list. Local standouts include Prairie Smoke and Common Yarrow. A living native groundcover does everything mulch does and then keeps doing it for free — covering soil, blocking weeds, and feeding wildlife as it goes. Match the spreader to the site (sun or shade, wet or dry), plant on tight centers so they close ranks in a season or two, and weed faithfully that first year while they fill in.
