Vertical gardens have become a growing trend in architecture and urban design.
Not only do they provide a unique visual appeal, but they also offer numerous functional and environmental benefits.
In this article, we will explore in depth the objectives of vertical gardens, their benefits both indoors and outdoors, real examples of their impact and some recommendations for installation and maintenance.
What are vertical gardens and what is their purpose?
Vertical gardens, also known as green walls or living walls, are vegetation-covered structures that are installed on vertical surfaces, such as interior walls or exterior facades.
These gardens can be created using a variety of plants, substrates and irrigation systems, adapted to grow vertically.
Definition and Concept of Vertical Gardens
A vertical garden is essentially a structure that supports plants grown on a vertical surface.
This concept makes it possible to create green areas in spaces where it would not traditionally be possible due to the lack of horizontal ground, such as in dense urban environments.
Main Objectives of Vertical Gardens: Aesthetics and Functionality
The main objective of vertical gardens, and one of the most demanded by our clients at Simular Green, is purely ornamental.
Vertical gardens create a ‘wow effect’, transforming common spaces into visually stunning areas.
As we observe, even today, a wall covered in green generates an immediate positive impact and captures the attention of those who observe it. However, beyond the ornamental purpose, vertical gardens serve other essential purposes, both indoors and outdoors.


Benefits of Vertical Gardens in Indoor Spaces
Vertical gardens not only improve the aesthetics of indoor spaces, such as offices and homes, but also offer significant benefits in terms of comfort and well-being.
Improved Work Environment and Employee Wellbeing
In one of our projects, we installed vertical gardens in offices so that they would be visible from any point.
Although the initial purpose was purely decorative, we quickly noticed that these gardens positively influenced the mood and productivity of the employees.
The constant presence of a green wall in the workspace can completely transform the atmosphere, creating a more relaxing and inviting environment.
This change can lead to an increase in job satisfaction, as having a fresh green view helps to reduce stress and improve concentration.


Increasing Relative Humidity and Air Quality
In addition to the emotional benefits, indoor vertical gardens help to improve environmental conditions.
In air-conditioned offices, which tend to dry out the air, vertical gardens provide additional humidity through evapotranspiration from plants and substrate.
This process not only increases the relative humidity of the environment, but also contributes to cleaner and fresher air, which is crucial for maintaining a healthy and comfortable workspace.
Outdoor Vertical Gardens: Impact on Urban Areas
Outdoor vertical gardens have an even greater impact in urban areas, where green space is limited. These gardens not only beautify building facades, but also offer numerous environmental and social benefits.
Example of a Vertical Garden in Alicante
Recently, we installed a vertical garden on a façade of approximately 400 m² in Alicante.
This project achieved an immediate visual impact, capturing the attention of passers-by and visitors.
The vertical garden covers a nine-storey building, and every time we visit it, we see people admiring it, taking pictures, and asking questions about it.
This ‘wow effect’ is undeniable and demonstrates the power of vertical gardens to transform an urban environment.


Promoting Biodiversity and Urban Sustainability
In addition to its visual impact, this vertical garden contributes significantly to urban sustainability. With more than 10,000 plants, it provides a habitat for diverse species of fauna and flora, promoting biodiversity in the heart of the city centre.
By using native vegetation or close to the local species of the Sierra de Alicante, we promote a biological niche that attracts insects and birds, creating a dynamic and healthy ecosystem.
These gardens also help to reduce air pollution, filtering particles and polluting gases such as CO2 and NOx, improving air quality in densely populated areas.
Installation and Maintenance of Vertical Gardens
To maximise the benefits of vertical gardens, it is essential to carefully consider installation methods and proper maintenance.
Types of Plants Used and Selection Criteria
The selection of plants for a vertical garden depends on several factors, such as location (indoor or outdoor), sun exposure, and local climatic conditions.
Succulents, herbaceous plants and some varieties of ferns are popular choices for vertical gardens due to their hardiness and low maintenance.
Construction Systems and Installation Techniques
There are various systems for constructing vertical gardens, from prefabricated modular structures to recycled wool felt systems that allow for more natural plant growth. Choosing the right system depends on factors such as the size of the project, the budget, and the specific objectives of the garden.
Conclusions and Recommendations for Installing Vertical Gardens
Vertical gardens not only add beauty to spaces, but also offer multiple functional and environmental benefits.
When considering the installation of a vertical garden, it is critical to evaluate both the visual impact and the functionality and maintenance required to ensure long-term sustainability.
Visual Impact and Functionality: What to Consider?
It is important to consider the environment where the vertical garden will be installed, as well as the specific objectives you wish to achieve, whether it is to enhance aesthetics, encourage biodiversity, or improve air quality.
With proper planning and the use of appropriate materials and plants, vertical gardens can be a valuable investment in both indoor and outdoor spaces.
