Build a Wall
A retaining wall creates planting opportunities when you select construction materials that allow you to plant in nooks and crannies along the wall's surfaces. Sedums spill from spaces in a 4-foot-tall retaining wall made of dry-stacked salvaged concrete.
Test Garden Tip: Other crevice-loving plants include creeping phlox, rock cress, thyme, hens-and-chicks, sweet alyssum, trailing lobelia, snow-in-summer, and candytuft.

Just Add Water
A waterfall is the ultimate way to take advantage of a slope. A steep slope is an opportunity to create a dramatic, sheer curtain of water. You'll need electricity nearby to bring life to the water pump but a good electrician should be able to help provide the power.

Display Your Favorite Containers
Take advantage of a change in grade to display your favorite potted plants on the outer edges of wide steps. Siting containers in well-traveled areas, such as entries, gives them greater impact.

Connect two levels with a curving stairway that minimizes the severity of the slope. Drought-resistant groundcovers and succulents prevent erosion on steep grades and make the journey more interesting.

Rocks and naturalistic plantings turn an eroding California hillside into a colorful oasis that blends with the surrounding desert habitat. Succulents such as Agave, Crassula, and Bulbine thrive here. Other good candidates for a dry hillside include Pennisetum, salvia, yarrow, and lamb’s-ear.

Plant roots are very efficient at anchoring loose soil on a slope. So turn a tough hill into a beautiful planting by selecting easy-care groundcovers that root into the bank wherever their stems touch soil. The dense mats they create will reduce erosion and weeds.

Deck the Hill
Transform a steep slope into valuable living space by straddling it with a multilevel deck. The contrast between natural plantings and a deck is always striking.
Test Garden Tip: Up the drama by building around an existing tree or planting one near the deck.

Make a Boulder Statement
Nestle clusters of boulders into the soil. They anchor portions of the slope and add natural beauty. Arrange rocks into groups staggered informally for a natural look. Bury the bottom one-third to one-half of each large rock to stabilize it. Pack soil firmly around the rocks, and finish with plantings.

Step It Up
Steps convert a slope from inaccessible to inviting. Wide steps that meander or zigzag up a steep slope are easier to climb than those that escalate rapidly.
Test Garden Tip: Begin building at the base of your slope if you're not sure where to add your stairs. Try climbing the slope along several different paths until you find the most comfortable route.

Build a Babbling Brook
A shallow slope is the perfect site for a burbling stream. Water can cascade down slopes that once seemed unmanageable, while controlling erosion and managing moisture levels.

Connect Activity Areas
A dry-stack stone wall and mortared stone steps join a garden house and spa set at different levels in the landscape. Lush plantings soften the hardscape, add color and fragrance, and invite exploration.

Create a Colorful Cliff
An abundance of spring bloomers turns towering terraces into a crazy quilt of cottage charm. Follow spring bulbs with summer- and fall-blooming perennials for extended bloom and season-long color.

Live It Up
Nestle an outdoor living space into your hillside. Steps to a raised flagstone patio provide a great view of the rest of the garden. A trickling stream with a series of cascades creates soothing sounds for relaxation.

Weave a Textural Tapestry
Create a sweeping swath of shrubs groundcovers for a low-maintenance slope solution. Most need trimming only once per year so you can almost literally plant them and forget them.

Create a Private Getaway
Colorful perennials and shrubs turn a utilitarian rock wall into a beautiful, naturalistic feature above an intimate retreat for two. Boulders support a border that includes Forest Pansy redbud, Japanese forestgrass, and lady's mantle.

Box It In
Use a slope to create garden art! Here, boxwood hedges create a visual masterpiece on a slope. The blue fescue between the hedges adds a fun contrast in form and color. Planting on the slope enables you to view the distinct planting pattern while enjoying a meal on the patio.
