Ground cover plants are an essential part of landscaping and have many uses in the garden. They can be used to carpet the garden, prevent erosion on slopes, cover shaded areas under trees, and prevent weeds from choking out other plants.

Not only that, but they can also add new colors and textures into the landscape. Many produce prolific blooms during the spring and summer growing seasons for an extra splash of color! We have formulated a list of the best ground cover plants to prevent weeds.

Autumn fern shrubs foliage fades to green once it reaches maturity in fall.
