A green wall installation can completely transform a space, visually, atmospherically, and even psychologically. Whether it’s in a residential home, a corporate lobby, or a public space, a living wall creates a statement that connects people with nature in a deeply impactful way. However, to ensure that your green wall installation is not just visually striking but also healthy and sustainable, selecting the right plants is essential. This isn’t simply about choosing the ones that look good. You must take into account environmental conditions, maintenance requirements, design intent, and plant compatibility.
If you’re considering creating a living wall but are unsure about which plants are suitable, this guide will walk you through the key considerations. We’ll also show how experienced providers like Aztec Plants can make this process smoother and more successful.

Understand the Environment of Your Green Wall Installation
The very first factor to consider is the location of your green wall installation. The environment will determine what types of plants can thrive in the space, how frequently they’ll need watering, and whether additional support systems like grow lights or irrigation will be necessary.
Natural light availability is crucial. A sun-drenched location may support light-loving species like succulents, rosemary, or kangaroo paw, but these same plants will suffer in shaded indoor spaces. For green walls installed indoors or in areas with limited sunlight, consider low-light-tolerant species such as ferns, peace lilies, pothos, or philodendrons. These plants are known for their adaptability and can thrive under fluorescent office lighting or indirect daylight.
Humidity and temperature also play a key role. A bathroom or indoor pool area, for example, is more likely to support high-humidity plants like calatheas or Boston ferns. On the other hand, air-conditioned offices with dry air may be more suitable for robust, drought-tolerant options like the ZZ plant or certain types of peperomia. Understanding the microclimate of your installation site is critical to choosing plants that will not only survive but flourish over time.

Consider the Watering Requirements of Each Species
Every plant has unique water requirements, and a successful green wall installation depends heavily on grouping compatible species together. A common mistake is mixing high-moisture and low-moisture plants, which leads to overwatering or underwatering and ultimately plant failure.
Moisture-loving plants like ferns, begonias, and creeping figs do well in vertical systems with built-in irrigation. These systems often include automatic timers, ensuring consistent moisture levels, which is especially important for high-maintenance greenery. Conversely, drought-tolerant species such as hoyas, rhipsalis, and string-of-pearls require minimal watering and are better suited for simpler systems with occasional manual watering.
Professional installers, such as those at Aztec Plants, design their green wall systems with plant compatibility in mind, ensuring the irrigation system is matched to the specific water needs of the selected plants. This balance makes maintenance easier and increases the longevity of the wall.

Define the Purpose of the Green Wall
Not all green wall installations are created for the same reason. Some are purely decorative, while others aim to promote well-being, purify the air, or even provide edible herbs. Defining your objective early will help narrow down your plant selection significantly.
If aesthetics are your priority, consider mixing various textures, colors, and forms to create a visually engaging display. Cascading vines such as pothos or ivy add movement and depth, while structured plants like bird’s nest ferns offer strong visual anchors. Colorful species like bromeliads or flowering herbs can be strategically placed for bursts of color.
For green walls with a wellness or sustainability focus, air-purifying plants like spider plants, peace lilies, and philodendrons are ideal. These species are not only beautiful but also filter out common indoor pollutants, contributing to a healthier indoor environment. If your green wall installation is meant to serve a practical purpose, such as growing herbs, then the plant list should include sun-loving, fast-growing edibles like basil, mint, parsley, and chives. Outdoor or kitchen-facing green walls are particularly well-suited for this type of installation.

Evaluate Maintenance Commitment
One of the most overlooked yet critical elements of green wall planning is maintenance. Different plant species come with vastly different care requirements. While all living walls require some upkeep, some plants demand far more attention than others.
If you or your facilities team prefer minimal upkeep, choose hardy, low-maintenance species such as pothos, ZZ plants, or philodendrons. These plants are resilient to changes in humidity and light and bounce back quickly from missed waterings or pruning delays. On the other hand, plants like maidenhair ferns and calatheas offer unique foliage but are sensitive to environmental changes. They require consistent humidity, filtered light, and careful watering. These high-maintenance options are better suited for green wall installations where regular professional maintenance is guaranteed.
Aztec Plants provides tailored maintenance plans with their living wall services, making it easier to include more complex plant species without compromising plant health or aesthetics.
Focus on Design and Layering for a Natural Look
Plant selection should not only be practical, it should also support the overall design of your green wall. A well-designed green wall installation mimics natural environments, incorporating layers, textures, and varying plant heights to create a dynamic visual effect.
Start by imagining the wall as a vertical ecosystem. Taller, structured plants should be placed toward the middle or upper levels, where they can frame the wall. Trailing or cascading plants can be positioned around the edges, allowing them to spill over and soften the structure’s appearance. Using plants with varying shades of green, alongside occasional accent plants with red or purple foliage, adds richness and contrast. Some designers also rotate flowering plants seasonally to maintain a fresh and evolving visual palette.
Layering plants with different shapes and textures, such as the flat, broad leaves of calatheas with the airy fronds of ferns, adds depth and helps prevent the wall from appearing too uniform. An experienced green wall designer, like those at Aztec Plants, will take this design philosophy into account and help select plants that not only grow well together but look exceptional when arranged in vertical space.

Think Long-Term: Soil, System, and Sustainability
No matter how beautiful the plants are, the green wall installation will only be as successful as the system that supports it. Soil quality, drainage, and structure are vital elements that influence plant health.
Use a light, well-draining potting mix rather than compact garden soil. A blend of premium potting mix with coir peat is a popular choice, offering good moisture retention without becoming waterlogged. The vertical wall system itself should support adequate drainage to prevent root rot while holding enough moisture to sustain the plants between watering cycles.
In terms of sustainability, selecting native or climate-adapted plants can significantly reduce water use and improve the wall’s resilience. These plants are already conditioned to local weather conditions and often require less intervention. In the UK, for example, native grasses, ivy, and shade-loving perennials are well-suited for both indoor and outdoor installations. This makes your green wall not only easier to manage but also more environmentally responsible.
