What is a living retaining wall?

A living retaining wall is a structural retaining wall system designed to support integrated vegetation, combining erosion control, drainage, and landscape aesthetics into one solution.

Are plantable retaining wall blocks structural?

Yes. Plantable retaining wall blocks are engineered to provide structural support while allowing integrated planting pockets for vegetation and groundcover.

What are the benefits of a vegetated retaining wall?

Vegetated retaining walls improve aesthetics, reduce heat absorption, assist with erosion control, soften hardscape environments, and create a more biophilic landscape design.

How do living retaining walls manage drainage?

Living retaining wall systems are designed with integrated drainage strategies that help manage hydrostatic pressure while supporting healthy plant growth.

Can retaining wall blocks support plants and succulents?

Yes. Plantable retaining wall systems are specifically designed to accommodate succulents, ornamental grasses, groundcovers, and other drought-tolerant plant materials.

Are lightweight retaining wall systems durable?

Modern lightweight retaining wall systems are engineered for durability and long-term landscape performance while reducing installation weight and complexity.

What types of projects are ideal for living retaining walls?

Living retaining walls are ideal for hospitality, commercial, multifamily, luxury residential, hillside, and erosion-control applications where aesthetics and performance are both important.

Do living retaining walls require irrigation?

Some living retaining wall systems benefit from supplemental irrigation depending on climate, plant selection, and project conditions.

Are plantable retaining walls better than traditional concrete block walls?

Plantable retaining walls offer aesthetic, environmental, and biophilic advantages over traditional concrete walls while still providing structural functionality.

Can living retaining walls help reduce erosion?

Yes. Living retaining walls help stabilize slopes, support drainage management, and reduce erosion through structural support and root-zone stabilization.

Your Hillside Deserves More than Concrete

Living retaining walls that hold grade and grow beautiful — installed by Elevation throughout Southern California. Certified Varden™ Installer.

When the Wall Becomes the Garden

Most retaining walls do one thing: hold soil. A living retaining wall does that — and then grows into something remarkable. We install Varden™ plantable retaining wall blocks, a system engineered over 30+ years specifically to turn grade changes into vertical botanical experiences. Each block holds a full cubic foot of growing soil, ready to be planted with groundcovers, succulents, native grasses, or edibles. Within a single growing season, the wall disappears beneath a cascade of living green.

"Planted and grown-over retaining walls are probably one of the most gorgeous things I've ever seen — and the reason I'm so passionate about this innovation."

— Mark Woolbright, Inventor, Varden™ Blocks | 30+ Years, 20 Patents in Living Wall Systems

The System

Three Reasons Elevation + Varden™ Changes Everything

After decades working with concrete retaining wall systems, the inventor of Varden™ blocks found a better path — engineered plastic that performs like concrete, ships like nothing else, and grows like a garden.

Varden block planting pocket with deep soil volume

🌿 Maximum Soil Volume

Each Varden™ block holds 1 full cubic foot of growing soil — the largest pocket volume of any plantable block on the market. Plants root deeply, access moisture naturally, and thrive without intensive irrigation.

Lightweight Varden pallet — 250 blocks, 800 lbs

💪 Featherlight. Seriously.

At just 3 lbs per block, a full pallet of 250 blocks covers 250 square feet of wall face and weighs only 800 lbs total — ideal for hillside properties and limited access conditions.

♻️ A Living Carbon Sink

A Varden™ living wall cools the microclimate through transpiration, filters stormwater, stores carbon in soil and roots, and provides habitat for pollinators.

Is It Right for You?

Your Property. Your Wall. Your Garden.

Living retaining walls work beautifully across a wide range of Southern California properties. Here's how to know if it's the right fit:

You have a slope, hillside, or grade change that needs retention
You want something that looks stunning, not industrial
Your site has limited equipment access — narrow paths, steep grades
You're building or renovating a custom home or luxury residence
You value sustainable, low-maintenance landscaping that gives back
You want curb appeal that doubles as ecological infrastructure
You're tired of bare gray concrete dividing your outdoor space

Material Matters

Why Engineered Plastic Outperforms Concrete Here

We understand the instinct to want something that feels permanent. But traditional concrete retaining wall blocks carry a heavy footprint through cement production, diesel transport, and equipment-heavy installation.

Varden™ blocks are made from structural-grade polypropylene — the same material used in automotive components and food-safe containers. UV-stabilized and chemically inert, they won't crack from freeze-thaw cycles, won't leach into soil, and are designed for multi-decade service life.

The real comparison isn't plastic versus concrete. It's a living, soil-and-plant system versus an inert, heat-absorbing mass of concrete.

What Grows Here

Southern California Plants That Thrive in Living Walls

The Varden™ block's oversized soil pocket means your plant palette is nearly unlimited. In Southern California's climate, these categories perform exceptionally well.

🌵 Succulents & Groundcovers

Sedums, ice plant, dymondia, and creeping thyme create dense, colorful coverage with minimal water.

🌿 Native Grasses & Perennials

Festuca, blue oat grass, and native groundcovers support local pollinators and thrive in SoCal's climate.

🍃 Vines & Trailing Plants

Ivy, vinca, honeysuckle, and euonymus cascade beautifully over a living wall for fast visual impact.

Common Questions

Living Retaining Wall FAQ

Varden™ blocks have been successfully tested in walls up to 10 feet, and we recommend them for landscape retaining walls up to 8 feet with geogrid reinforcement. Walls over 3 feet may require a permit and engineered plans depending on your municipality.

With the right plant selection, most Varden™ walls show substantial coverage within a single growing season. The oversized soil pocket helps plants root deeply and establish quickly.

We typically recommend a simple drip system during establishment. Once established with drought-tolerant Southern California plant species, many walls require less supplemental water.

In this application, structural-grade polypropylene provides major advantages in weight, transport, access, planting volume, and environmental performance when paired with living soil and plants.

Generally, walls under 3 feet of exposed height may not require a permit in many municipalities. Walls 3 feet and above typically require a permit and may require engineered drawings.

Installed pricing depends on wall height, length, site accessibility, plant selection, and whether engineering is required. Use the calculator as a starting point, then schedule a consultation for a project-specific quote.
