Native Groundcover Plants in Connecticut
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 Connecticut and the wider flora of the Northeast and hardy through zones 5–7 — proven performers for Connecticut's cool, humid continental climate across Northeastern Coastal Forest, not a generic list. Local standouts include Foamflower and Wild Geranium. 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.
