Choosing the right plants for a slope is about more than just good looks—it’s about keeping your soil where it belongs! These popular picks are perfect for steep spots because they’re tough, easy to maintain, and great at stabilizing the earth.

++English Ivy (Hedera helix)
When it comes to covering a hillside, many gardeners turn to the classics. English Ivy is a go-to groundcover for a reason. This vigorous grower doesn’t just climb trees; it spreads horizontally across the ground, creating a thick mat. Its root system is fantastic for giving loose soil some much-needed structure. Once it’s established in the right spot, it’s pretty much “set it and forget it,” though you’ll want to give it a trim if it starts venturing where it shouldn’t!
++Thyme (Thymus)
Who says a functional slope can’t be delicious? Planting thyme is a brilliant way to green up a hill while anchoring the soil with its dense roots. Plus, you get the added bonus of that amazing Mediterranean fragrance every time you walk by. From June through October, you’ll see tiny white or pink flowers, but even when it’s not blooming, the delicate green foliage looks sharp. It’s a kitchen garden and erosion control all in one!
++Dog Rose (Rosa canina)
If you want a bit of color on your hillside, try mixing groundcovers with flowering shrubs like the Dog Rose. This wild rose is famous for its bright red rosehips and incredibly deep roots. It digs in deep, even on steep inclines, making it a champion at securing loose ground. It’s so effective that it’s often used on sandy coastal islands to keep the dunes in place—so you know it can handle your backyard slope!
++Butterfly Bush (Buddleja)
For a real showstopper, the Butterfly Bush is a fantastic choice. It loves a sunny spot and is surprisingly low-maintenance. As the name suggests, planting a Butterfly Bush is a huge win for your local ecosystem, drawing in bees and butterflies all summer long. It handles steep grades like a pro, helping to knit the hillside together while providing a massive pop of color.
++Scotch Broom (Cytisus scoparius)
Scotch Broom is legendary for its soil-stabilizing roots. While it’s famous for those bright, cheery yellow blooms, it’s actually a member of the pea family. Gardeners love it because it stays relatively compact and doesn’t get too tall, which is exactly what you want on a slope. It’s a tough, hardy shrub that brings a sunny vibe to any difficult landscape.
++Cranesbill Geranium (Geranium)
Hardy geraniums (not to be confused with the annuals!) are beautiful, easy-going perennials. They’ve been garden favorites for centuries because they can turn a neglected hill into a floral carpet in no time. Their roots do a great job of holding the earth, and they play well with other groundcovers. Just a heads-up: if you’re mixing them, make sure your groundcover isn’t so aggressive that it crowds out the geraniums!
++Privet (Ligustrum)
If you’re looking for something a bit more structured, Privet is a classic. It grows into a dense, leafy hedge that provides excellent erosion control. The best part? With the right pruning, you can keep it looking super neat and tidy. It’s a great way to bring a sense of order and clean lines to an otherwise wild or uneven hillside.
%%Serviceberry (Amelanchier)
While groundcovers and shrubs are the usual suspects for slopes, some small trees work beautifully too. The trick is picking something that doesn’t get too massive for the space. The Serviceberry is a perfect candidate. It’s naturally adapted to rocky, sloped environments and stays at a manageable size, offering pretty white flowers in the spring and great fall color without overwhelming your yard.
