Low, spreading natives that knit together to cover bare ground, smother weeds, and replace thirsty lawn or mulch. Oklahoma sits in a landscape of Cross Timbers & mixedgrass prairie, and the natives that thrive here are the ones built for its continental, hot summers character. The list below — led by Foamflower and Wild Geranium — is filtered to species genuinely native to Oklahoma and the wider flora of the Great Plains and hardy through zones 6–8. 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.
