If you live in a sloppy area, or you plan to grow your plant on a slope, there are certain factors you should consider, namely, erosion control and slope stabilization.
Ensure the plants are deep-rooted shrubs and trees, which help stabilize the slope and make use of more shallow-rooted ground covers, which will help to cover the slope.
Water will always find its way on a slope. On a more precise note, a good amount of it tends to run off before it soaks in, making the sloppy ground problematic for planting.
However, drought tolerant plants for slopes, such as sedum album, epimedium rubrum, sedum acre, armeria maritima, sedum oreganum, phormium tenax, etc.; will make things easier for you. These plants will do well under hot, dry, sunny situations.
Let’s briefly discuss more about these drought tolerant plants that are ideal for sloppy areas!
Common Drought Tolerant Plants for Slopes
