What is a Vertical Garden?

A vertical garden, also known as a living wall or green wall, is a method of growing plants up a wall or other vertical surface. This method is not only utilized for space-saving purposes, but also to create a visually appealing feature that contributes positively to both aesthetics and the environment.

Main Components of a Vertical Garden:

  • Support structure: This is the foundation that holds up the plants against the wall, which could be panels or tiered planters.
  • Growth medium: This comprises the soil or hydroponic materials where the plants grow.
  • Irrigation system: It is responsible for watering the plants. In an advanced vertical garden, there might be a built-in irrigation that’s automated.
  • Plants: The selection of plants will depend on the location, sunlight availability, garden size, and personal preferences.

Examples of Vertical Gardens

  1. Indoor Decor: Some people incorporate vertical gardens indoors to bring a sense of nature into their home and increase oxygen levels. Often, these indoor gardens will feature shade-tolerant species, such as ferns or mosses.
  2. Outdoor Statement Walls: Larger vertical gardens can be created outdoors and used to make a statement. For instance, the vertical garden at the Musée du Quai Branly in Paris covers an entire outer wall of the building.
  3. Urban Farming: In a city with limited space, vertical gardens are a great way to grow your own food. They can turn a small balcony into a green oasis with herbs, vegetables, and even edible flowers.
  4. Roof Gardens This is another form of vertical gardening that allows buildings to make good use of roof space for growing plants. This can provide a cooling effect for the building, promote biodiversity, and improve the aesthetics of a city landscape.

Vertical Gardens are an innovative, space-efficient solution for those who aim to maximize greenery in minimal spaces, contributing to both design and ecological benefits.

What are the different types of vertical garden structures?

There are several types of vertical garden structures ranging from wall-mounted systems to freestanding designs which are suitable for different environments and needs. These structures vary in complexity, aesthetics, cost, and the amount of greenery they can host.

Wall-Mounted Gardens

Wall-mounted garden structures are attached directly to a wall and are most commonly found in indoor vertical gardens. A popular example of this type is living walls or bio-walls, where the wall structures can support a wide variety of vegetation.

Pocket Gardens

Pocket Gardens use a type of vertical structure where plants are housed in singular pots or “pockets”. These pockets are then attached to a panel that hangs on a wall. An example is the WallyGro wall planters that hang directly on fences or walls.

Trellis Gardens

A trellis garden is another type of wall-mounted garden structure. It is typically made of latticework where climbing plants, like ivy or roses, are trained to grow into and around the framework.

Freestanding Gardens

Freestanding garden structures are unattached and can stand independently. They can be moved and rearranged easily, making them a flexible choice for both indoor and outdoor vertical gardening.

Vertical Garden Towers

A vertical garden tower is a self-standing structure, often used for growing herbs and small vegetables. Companies like Tower Garden sell vertical gardening systems designed for urban bonnie plants.

Tiered Vertical Planters

Typically made from wood or plastic, these vertical garden structures consist of tiers or levels of planters stacked on top of each other in a pyramid shape. Each tier can house different plants, and their elevation allows for optimal sun exposure.

Container-Style Gardens

Container-style gardens involve vertically stacking containers, like plant pots or boxes, to create a green structure. This type is quite popular for balcony gardening where space is limited.

Stackable Pot Towers

These vertical structures can be made by stacking pots, each with their own plant, on top of each other. The tower format saves horizontal space while ensuring each pot gets sunlight exposure.

Shoe Organiser Gardens

A quirky approach to vertical gardening involves repurposing over-the-door shoe organizers. Each shoe pocket serves as a small planter for herbs, flowers, or small vegetables.

In summary, the type of vertical garden structure chosen depends largely on the available space, desired aesthetics, and the specific needs of the plants being grown.

What is the best location for a vertical garden?

The best location for a vertical garden is largely dependent on the specific light, temperature, and moisture requirements of the plants you wish to grow. However, an ideal location will typically be a place with enough sunlight, sturdy support, easy access for maintenance and good ventilation.

Indoor Vertical Gardens

Indoor vertical gardens bring a piece of the outdoors inside, enhancing the aesthetics and providing extra oxygen. They can turn any living or workspace into a tranquil haven.

Living or Dining Rooms

Living and dining rooms often have large wall spaces and receive indirect sunlight from the windows, making them good locations for an indoor vertical garden.


The kitchen can be an ideal spot for a small vertical herb garden. Having herbs on hand not only is convenient for cooking but also adds a wonderful aroma to the kitchen space.


A bathroom with sufficient light can house humidity-loving plants, transforming this functional space into a natural sanctuary.

Outdoor Vertical Gardens

Outdoor vertical gardens maximize growing spaces and can add a touch of nature to urban living.

Balcony or Patio

A small balcony or patio is an excellent location for a vertical garden. It not only beautifies the area but also provides privacy.

Garden Walls or Fences

Placing a vertical garden against an existing garden wall or fence can provide ample space for the plants to grow. A vertical garden on a wall facing the sun will give most plants the light they need.

Regardless of location, remember that the key to a thriving vertical garden lies in the right balance of light, temperature, and moisture. Therefore, it is essential to bear in mind the specific needs of the plants you are planning to grow in your vertical garden.
