7. Lamb’s Ear (Stachys byzantina)
Soft, silver leaves and quick-spreading growth make Lamb’s Ear both ornamental and effective at smothering unwanted weeds.
8. Catmint (Nepeta spp.)
A tough, fragrant perennial that forms a lush mound—catmint not only keeps weeds down but attracts bees and butterflies.
9. Coneflower (Echinacea purpurea)
Tall, sturdy, and self-reliant, coneflowers shade the ground below with their large leaves and create an unwelcoming zone for weeds.
10. Coral Bells (Heuchera spp.)
Great for part-shade areas, coral bells form dense clumps of colorful foliage that add beauty while protecting your soil.
11. Creeping Jenny (Lysimachia nummularia)
This fast-growing spreader covers the ground like a golden-green blanket. Excellent for moist spots or around rocks where weeds often sneak in.
12. Bee Balm (Monarda didyma)
An aggressive grower (in the best way), bee balm forms colonies that crowd out weeds while feeding pollinators all summer.
13. Ajuga (Ajuga reptans)
Also known as bugleweed, ajuga grows fast, stays low, and fills empty patches quickly. Its glossy leaves and purple blooms make it as beautiful as it is useful.
14. Coreopsis (Coreopsis lanceolata)
With its sunny yellow blooms and clumping habit, coreopsis spreads just enough to form a weed-resistant barrier that’s also drought-tolerant.
Tips for Success
-
Plant close together: The denser your planting, the less room weeds have to grow.
-
Use mulch at first: Until your “warriors” are established, mulch helps block weed seeds.
-
Choose perennials suited to your climate: Once settled in, they’ll thrive with minimal effort.
