With the latter, inclines and odd shapes can increase erosion or cause moisture to drain fast. So, if you have that problem, here are the best plants for slopes, hillsides and banks that will grow where most plants won’t.
What Kind of Plants are Good for Slopes, Banks and Hillsides?

The key is finding the right plants.

- Groundcover – low growing are ideal. Fast growing are great as well. This lets you blanket the space. Of course, choose the color you want and the style of plant you prefer.
- Shrubs and trees – these help add a bit of character. Having all low growing groundcover can get boring and won’t provide enough variety to make that area lovely to look at.
- Grass – some people like using grass. While this works, consider the difficulty of mowing and maintaining it on a slope.
- Drought tolerant plants – slopes and banks will cause water to run downwards. As such, the area won’t hold moisture well.
- Shade plants – this only applies if your sloped area faces away from the sun most of the day or doesn’t get long hours of sunlight exposure.
- Low maintenance plants – sloping areas are a hassle onto themselves. Don’t add fussy or finicky plants that will make your life more difficult.
