Beyond Moss: Unlocking the Power of Plant Diversity in Biophilic Design

The biophilic design movement has gained tremendous momentum in recent years, with moss walls becoming a popular feature in commercial and residential spaces. While moss installations offer significant benefits, there's a compelling case for expanding beyond single species approaches to embrace the rich diversity found in nature. Biodiverse foliage gardens—incorporating various preserved plant species beyond moss—can create more dynamic, visually interesting, and psychologically beneficial environments that better mimic the complexity of natural ecosystems.

Beyond the Moss Wall: Understanding Biophilic Diversity

Moss walls have become justifiably popular in biophilic design due to their striking visual impact and relatively simple implementation. However, nature itself rarely presents as a monolithic expanse of a single species. Natural environments feature diverse ecosystems with varying plants, textures, colors, and forms—all working together to create rich, complex landscapes that stimulate our senses and nurture our well-being.

‍

Research in environmental psychology suggests that environments mimicking this natural diversity can provide enhanced psychological benefits. A study published in the Journal of Environmental Psychology found that spaces featuring a variety of natural elements triggered more positive emotional responses than those with less diversity, even when the total amount of greenery remained constant.

The Science Behind Biodiversity Benefits

The human brain evolved in highly complex natural environments, which may explain why we respond so positively to biodiverse spaces. Neuroscientific research into this phenomenon reveals several key mechanisms at work:

Soft Fascination: Diverse natural environments provide what attention restoration theory terms "soft fascination" -stimuli that capture attention gently without demanding concentrated focus. This allows the mind's directed attention facilities to replenish, reducing mental fatigue.

Varied Sensory Input: Different plant species offer varied textures, shapes, and colors, providing rich sensory information that engages the brain more fully than uniform environments. This varied sensory experience can enhance cognitive function and mood.

Biomimetic Patterns: Diverse foliage creates natural fractal patterns and organic arrangements that research has shown to reduce stress and improve cognitive performance. These patterns resonate with our innate preferences shaped through evolutionary history.

Emotional Regulation: Studies show that exposure to varied natural elements can help regulate emotions, reducing anxiety and promoting a sense of calm and well-being.

Cultivating Wellness Through Biodiverse Gardens

Biodiverse preserved gardens offer specific wellness benefits that extend beyond what can be achieved with moss alone:

Enhanced Psychological Restoration: Research suggests that plant diversity correlates with enhanced psychological restoration. Different plant species stimulate different cognitive responses, creating a more comprehensive restorative experience.

Improved Visual Interest: Varied foliage creates dynamic compositions with different heights, textures, and forms, maintaining visual interest over time and preventing habituation (when the brain begins to filter out constant stimuli).

Seasonal Connections: Diverse gardens can incorporate elements reminiscent of different seasons, helping maintain connections to natural cycles even in climate-controlled environments.

Cultural and Personal Associations: Different plant species may carry cultural or personal significance, potentially triggering positive memories and associations that enhance emotional well-being.

Neurodivergent Considerations: For neurodiverse individuals, biodiverse gardens provide a balance of stimulating and calming elements that can help accommodate different sensory needs.

Case Studies: Biodiversity in Action

Several notable projects demonstrate the impact of biodiverse foliage gardens:

Nashville International Airport: The world's largest preserved garden installation features remarkably biodiverse compositions spanning 105 feet on each side of the security screening lanes. These gardens showcase local landmark bridges while incorporating sound motifs reflecting Nashville's musical heritage. With varying hues, layers, and textures, these expansive installations provide a calming presence for the 20 million annual passengers navigating the stressful security process.

‍

Essentia Health St. Mary's Medical Center: This award-winning installation spans three stories with forest species, ferns, and eucalyptus over a moss canvas. The tapestry of greenery mimics the vistas of Duluth's hillsides visible through the windows, creating a natural haven that helps patients feel welcome and restored -crucial elements in the healing process.

‍

Corporate Agriculture Company Headquarters: The Arlington VA office of a responsible agriculture and crop science company features lush, biodiverse garden installations that reflect their green ethos. Located in the lobby and break areas, these gardens incorporate moss, ferns, and colorful flower foliage, bringing texture and depth while underscoring the organization's commitment to environmental responsibility.

Implementation Strategies for Maximum Benefit

When incorporating biodiverse gardens into your space, consider these strategies to maximize their impact:

Strategic Positioning: Place biodiverse gardens in high-visibility, high-impact locations where they can serve as focal points and conversation starters. Areas of transition, such as entrances and lobbies, are particularly effective locations.

Scale Appropriately: Consider the size of your space when determining the scale of your installation. In larger spaces, substantial installations create impactful statements, while smaller spaces may benefit from more intimate garden features.

Connect with Local Ecology: Choose preserved plant compositions that reference local natural environments, creating a subtle connection to the surrounding ecosystem even in interior spaces.

Consider Function: Design biodiverse gardens with specific functions in mind—whether creating calm in high-stress areas, enhancing creativity in collaborative spaces, or providing acoustic benefits in open-plan environments.

Material Health: Ensure your preserved garden provider offers comprehensive third-party testing and certifications. Garden on the Wall^® stands as the only provider offering Health Product Declaration (HPD v2.3), compliance with California Department of Public Health's VOC standards, 100% Bio-Based Test Results (ASTM 6866), and Red List Free certification for their whole garden system.
