A bare slope can lose more than mulch after a hard Michigan rain. As water moves downhill, it carries topsoil, exposes roots, creates ruts, and can eventually undermine lawn edges, planting beds, or hardscape features below. The best slope stabilizing plants slow that water down and hold soil in place with a dense network of roots – but only when the plant choice matches the slope’s sun, soil, moisture, and grade.
For Macomb-area homeowners, the goal is usually not to turn a hillside into a wild planting. It is to create a clean, durable landscape that looks intentional, is manageable to maintain, and protects the investment around it. The right planting plan can do that. On a steep or actively failing slope, however, plants are part of the solution, not the entire solution.
What Makes a Plant Good for Slope Stabilization?
Plants control erosion in two useful ways. Their leaves soften the force of rainfall before it hits exposed ground, while their roots bind soil together and improve its ability to absorb water. The most effective planting designs layer different root types: low groundcovers across the surface, ornamental grasses with fibrous roots, and shrubs with deeper, spreading root systems.
A plant’s mature size matters as much as its name. A single large shrub with open space around it will not stabilize a bank as effectively as thoughtfully spaced plants that grow together into broad coverage. Evergreen foliage can also help protect soil through winter, when dormant turf and frozen ground leave slopes vulnerable to runoff during thaws.
Conditions decide what will thrive. A sunny, dry slope near a driveway needs a different plant palette than a shaded backyard grade where water collects after storms. Before planting, identify where the water starts, where it travels, and whether it has a safe place to exit.
10 Best Slope Stabilizing Plants for Michigan Properties
Creeping Juniper
Creeping juniper is a practical choice for full-sun slopes with well-drained soil. Its low, spreading evergreen branches cover exposed ground year-round, helping reduce splash erosion and keeping a planted bank looking finished in winter. It is especially useful along sunny foundations, berms, and slopes where mowing would be awkward.
Juniper does not tolerate consistently wet ground. If water stands on the slope, solve the drainage issue first or choose a moisture-tolerant shrub instead.
Fragrant Sumac
Fragrant sumac, particularly low-growing selections, is one of the strongest shrub options for sunny to partly shaded banks. It spreads gradually, develops a broad root system, handles dry soil well once established, and provides attractive fall color. Its natural, mounded habit also makes it useful where homeowners want erosion control without the formal look of a continuous hedge.
Give it room to spread. It works best on larger slopes and outer bed edges where its mature width will not crowd walkways or patios.
Red Twig Dogwood
For slopes that stay moist or receive runoff, red twig dogwood brings both function and winter interest. This adaptable shrub tolerates wet soil better than many slope plants, and its stems help slow surface water as the shrub matures. The red branches stand out in winter, when much of the landscape is dormant.
Red twig dogwood needs periodic renewal pruning to stay dense and colorful. It is better suited to a naturalized edge, drainage swale, or larger planting area than a small, tightly controlled bed.
Little Bluestem
Little bluestem is a native ornamental grass with fine texture, blue-green summer foliage, and warm coppery color in fall. More importantly, its fibrous roots help hold soil on dry, sunny slopes. It is a strong choice for homeowners who prefer a lower-water, naturalistic planting design.
Like many ornamental grasses, it is typically cut back in late winter or early spring. Leaving it standing through winter provides visual interest and keeps some cover on the slope during the coldest months.
Switchgrass
Switchgrass is taller and more substantial than little bluestem, making it useful on broad slopes where larger plantings are needed. Its deep root system helps improve soil structure, and established clumps tolerate sun, wind, and periodic moisture. It can create a soft screen along a property edge while supporting the ground below.
Choose compact cultivars for residential settings. Full-size switchgrass can become too tall for a front-yard bed or a narrow area beside a driveway.
Pennsylvania Sedge
Shady slopes are often difficult because turf thins under trees, but Pennsylvania sedge offers a refined alternative. This low-growing, shade-tolerant sedge forms a soft green cover and works well beneath mature trees where grass struggles. Its fibrous root mass helps protect surface soil without competing as aggressively as some traditional groundcovers.
It prefers woodland-like soil that is not constantly soggy. A light layer of shredded mulch between young plants can protect the bed until the sedge fills in.
Creeping Phlox
Creeping phlox provides dense, low coverage and a colorful spring bloom on sunny or partly sunny slopes. It is well suited to the upper portions of a slope, where soil is often drier and drainage is better. When planted in groups, it softens stone edges and gives a more finished appearance than exposed mulch alone.
It is not the best choice for a large, unstable bank by itself. Use it as a surface-covering layer alongside shrubs or grasses that provide stronger root structure.
Bearberry
Bearberry is an evergreen groundcover worth considering for sunny, sandy, acidic, well-drained sites. Its trailing stems, leathery leaves, and small red berries offer year-round interest, while its low habit helps shield bare soil. It is particularly useful where poor soil and dry conditions make other groundcovers unreliable.
This is a site-specific plant, not a universal answer. Heavy clay, poor drainage, or frequent irrigation can cause it to decline.
Daylilies
Daylilies are familiar for a reason: they are durable, easy to understand, and useful on moderate slopes with sun to partial sun. Their clumping growth and fibrous roots help reduce erosion, while their summer flowers add color to a practical planting. They pair well with grasses and low shrubs in a layered bed.
Avoid relying on one row of daylilies to solve a drainage problem. They are best used as part of a mixed planting, especially on slopes that are not excessively steep.
Wintercreeper Alternatives: Native Groundcovers
Some older landscapes use wintercreeper for fast coverage, but it can become aggressive and is not a preferred choice where it may spread beyond the intended bed. A better long-term approach is to use regionally appropriate groundcovers such as Pennsylvania sedge in shade or creeping phlox in sun, then combine them with shrubs and grasses suited to the site.
The fastest-growing plant is not always the best slope plant. Predictable growth, manageable maintenance, and compatibility with the rest of the property are more valuable over time.
Plants Cannot Fix Every Slope Problem
If the slope has deep washouts, exposed roots, cracking soil, leaning retaining walls, or water flowing toward the home, do not plant over the warning signs. These conditions may call for grading, drainage improvements, a dry creek bed, erosion-control fabric, boulders, or a properly engineered retaining wall before landscape installation begins.
A simple test is to watch the area during a steady rain. If water is sheeting across the surface, carving channels, or pooling at the bottom, the water path needs attention. Downspouts that empty onto a slope are a common cause of erosion and should be redirected to an appropriate outlet.
For a manageable planted slope, preparation makes the difference. The soil should be shaped so water moves gently rather than rapidly. Plants need to be installed across the slope in staggered groups, not in straight vertical rows that can direct water downhill. Mulch should be applied lightly enough that it does not wash away, and biodegradable erosion-control blankets can protect bare soil while roots establish.
A Better Way to Plant and Maintain a Hillside
New plantings need consistent watering through their first growing season, even plants described as drought tolerant. Water slowly so moisture reaches the root zone instead of running off the surface. Once plants establish, inspect the slope after major storms, refill any small erosion areas promptly, and keep mulch out of swales and drain paths.
The strongest designs rarely depend on one plant. A lower evergreen groundcover, grouped grasses, and strategically placed shrubs create better coverage, more visual depth, and a wider range of root systems. They also make the slope feel like a designed part of the property rather than a problem area hidden behind mulch.
When erosion, drainage, and curb appeal are all part of the same project, it helps to have one team evaluate the full picture before work begins. A well-planted slope should give you confidence every time heavy rain moves through – not another reason to look out the window and worry.
