Bunchberry (Cornus Canadensis) 

While the majority of plants will require a benchmark of sunlight to grow and glow, the bunchberry is towing a different path in terms of such preferences.

It thrives well in a shaded area so if you are looking for a shade-loving plant, you’ve found one in the bunchberry. Most times, your sloppy landscape is heavily shaded and most of the plants you intend using for ground covers are all sun-loving, this is a rescue.

It’s a deciduous shrub native to North America but it doesn’t mean you can’t use it in your region. You need to keep up with trimming, however since it grows so proud at 9 inches maximum height.

The flowers display their glorious presence from May to July in white colors. It is deer-resistant and rabbits has got nothing on it equally. Native to woody areas, it is perfect for shady woodland gardens. And by the way, it has fruits but we aren’t certain if they are edible yet.

Spotted Deadnettle (Lamium maculatum) 

With its dazzling silver leaves, the dead nettle is a premium choice for ground covers in most regions where it is favorable but comes with a little bit of a challenge, it is very invasive in certain landscapes or soil textures.

It is wise to consult a landscaper first before getting the spotted dead nettle for ground covers. It can be used for ornaments with a twofold variety in that it reflects its charming blossoms colorfully.

There is the purple color which is a variant or best known botanically as a cultivar. It is named “purple dragon” and the pink variant or cultivar which has the beautiful “silver shield”.

They grow to a maximum height of 9 inches so you ditch the idea of getting lazy when it comes to pruning once in a while. The flowers arrive in all their glory from May to July.

The flowers come in the color variants of pink, white, red or purple. There are restrictions to planting it across some regions of the United States due to its invasive nature, be guided before using it.

Sweet Woodruff (Galium odoratum) 

If you love lush greenery with a touch of white standing out, then you are looking for the Sweet Woodruff. It is a low-maintenance ground cover if you are not ready to get involved in routine maintenance culturing.

It has a great fragrance to add to its pretty properties and perhaps compensate for its invasive properties. Invasive in some areas, you don’t want it encroaching into restricted territories. You need a consultation from relevant authorities if it’s okay for your soil.

You should note however that moist soils provide a safe haven for it thrive and if your soil is moist, it can display its invasive properties and possibly go overboard with it. Beyond it’s imposing tendencies, it’s a great plant and a perfect ground cover for dry shades like under trees.

Height might come as another challenge, at 12 inches maximum, it is indeed a proud outstanding plant and needs to be tamed regularly.

Flowers are a given, her flowers blossom in white colors when spring sets in. Since it loves to show its imposing tendencies in wet soils, planting it in dryland areas where it can be starved of substantial moisture can be a good way of limiting its invasive properties. This doesn’t mean you should starve it of water entirely, it would mean calling it a day.

You should be able to come to a reasonable compromise between watering and starving. Too much of each can ruin the plant and there’s the need for a balance. 

Ground Cover for Slopes: Pros

  • Has a pleasant fragrance 
  • Weed control 


  • Has the highest maximum height at 12 inches which calls for constant pruning

It’s a broadleaf woody-stemmed plant that stays evergreen all year round. Typically, it is used to grace retaining walls or in knot gardens. It has a great affinity for the sun and you dare not rip it off that pleasure else it will say its goodbyes.

It is arrogant and can extend to 12 inches in height. When it decides to bloom with flowers in July, lavender, and pink become its favorite colors to use.

You need to keep up with some level maintenance here considering how high the plant grows. If you don’t trim regularly, the plant will have no leash in growing bushy and shrubby. This is a compromise on the ideal nature of ground covers for slopes, so maintenance is necessary but not overly. 


  • Weed control 
  • Away from the norms


  • Maximum height of 12 inches require regular maintenance

What is the quickest growing ground cover?

The fastest growing ground cover is the annual flowering plant, Phlox Drummondi. This species can be found in gardens, roadsides and other disturbed areas throughout much of the United States. In the Southeast, this species can be found along roadsides and in fields from Virginia to Florida and west to Missouri. The flowers are usually pink or lavender but can also be white, yellow or mauve.

Another largest ground cover is the perennial herb, Salvia splendens, which grows up to 8 inches tall. This species is found throughout the United States, except for Alaska, Hawaii, and the West Coast. It is found in a variety of habitats, including roadsides, waste areas and disturbed sites. It prefers a sunny location.

What do you plant on slopes for erosion control?

When you’re on a slope, you need to be able to control erosion and sediment. So we use vegetative cover to help with that. We use grasses and small shrubs, or we may use trees.

For areas where we have the ability to create more soil, we will add organic matter like compost or manure. 

The purpose of that is to create an environment that’s more hospitable to plants. So when the plants grow, they don’t have to compete for water.  In a flood-prone area, there are two things that we need to control erosion: one is to build up the soil and the other is to hold the water.

We will use shrubs to hold the water. We also will use woody plants. We will plant trees where it’s a steep slope, because you can get trees that are very tolerant to the soils on slopes. They don’t mind the wet conditions and they don’t mind the acidity.

Does creeping thyme spread fast?

It is possible to grow thyme from seed, but you should have a green thumb for that. It grows very slowly, so it's not going to become invasive in the first place. If it gets too big for your liking, you can cut it back. Or if you live near the sea, you could leave some of it in the ground and let it die back in winter.

But it will always come back next year.

Does creeping thyme come back every year?

It really does. It is such a bright green color in the spring and summer, then it turns to a deep purple-ish-grey in the fall and winter. It comes back in the spring as a light grey, with tiny yellow flowers.

It is a pretty, yet subtle plant that grows very well in my garden. I have to keep it trimmed so it doesn't grow too big. I can see why it would be such a good choice for a garden, it is hardy, easy to grow and looks so pretty.

Ground Cover for Slopes,

The creeping thyme comes as the ultimate choice in our verdict having virtually no anticipated problems and barely grows above 3 inches fitting the low-maintenance description of ground covers. It is also used as a favorite for landscaping and useful in weed control.
