Definition of Walled Garden Examples and Benefits

Plants usually need sunlight, water, and nutrients in order to grow. In other words, they require the necessary elements for their survival and propagation. A Walled Garden is a greenhouse or a conservatory that replicates these basic growing requirements, especially conditions such as light, temperature, and humidity. Such gardens are used as display cases in botanical gardens around the world but can also be found in some large homes.

The Definition

The word “Walled” in the name Walled Garden refers to the fact that these gardens are isolated from the outside world and have controlled growing conditions. This is done in order to protect the plants inside from diseases, pests, and other environmental threats. The walls can be made of glass, metal, or wood and can be as small or as large as needed. These gardens are sometimes also called “greenhouses” or “conservatories”.

The Examples

There are many different types of walled gardens. Some are very simple while others are quite elaborate. Here are a few examples:

The Medici Villa di Castello

Cosimo I de Medici, Grand Duke of Florence built this walled garden in 1630 as part of an elaborate reservoir system to store rainwater and provide drinking fountains for his people. The architecture is stunning with ovals patterns on topography that was designed by architects CosiminoItaliano – they use travertine stone for high walls made from sturdy material thoughtfully providing privacy while also being aesthetically pleasing at once. There are flowers everywhere; most importantly however are those who live inside these grounds: Castello contains numerous fruit trees including oranges which can be found right outside my window here today.

The Orangerie at the Palace of Versailles

The Orangerie was built in 1684 to house King Louis XIV’s orange trees during the winter months. It is a two-story building with an oval-shaped footprint and is made entirely of stone. The roof is covered in lead, which helps to keep the temperature inside the conservatory stable. Today, the Orangerie is used as a gallery to showcase art pieces and other works of historical significance.

The Palm House at Kew Gardens

The Palm House at Kew Gardens in London was designed by Decimus Burton back in 1844 and originally housed a variety of tropical plants from around the world. Made from cast iron and glass, this stunning piece of architecture is one of the largest examples of a walled garden in the world, with huge curved windows that allow sunlight to filter inside. Today, it remains a popular tourist attraction and is home to numerous species of tropical plants and trees.

The New York Botanical Garden

The New York Botanical Garden is a large walled garden that was founded in 1891. It covers an area of 250 acres and contains a wide variety of plant life, from flowers and trees to vegetables and herbs. There are also many different buildings on the grounds, including a conservatory, a museum, and several greenhouses. The garden is a popular tourist attraction and sees millions of visitors every year.

The Benefits

There are many benefits to having a walled garden. For one, these gardens provide a controlled environment for growing plants that may not be able to survive in the wild. Here are some of the benefits of the walled garden:

Protection from pests and diseases

Many plants require specific conditions in order to grow successfully, such as the right amount of light, moisture, and nutrients. A walled garden can provide these conditions with relative ease, ensuring that your plants are healthy and well-cared for at all times.

Maintaining biodiversity

Walled gardens can also be used to help maintain biodiversity by cultivating rare or endangered plants from around the world. These plants are often much harder to find in their natural habitats, but they can be grown and preserved in a controlled environment like a walled garden.

Greater crop yields

In addition to growing rare plants, walled gardens can also be used to help farmers and gardeners maximize their crop yields. With the right conditions and care, you can produce much higher quality plants that yield more fruit and vegetables.

Improved air quality

Plants play a vital role in purifying the air, and a walled garden can help to improve air quality in your home or office. By growing plants that are known to filter out harmful toxins and pollutants, you can create a cleaner and healthier environment for yourself and others.

Better control over the environment

Finally, walled gardens allow for much greater control over environmental factors like temperature, humidity, water levels, and soil quality. This control can be crucial for ensuring that plants thrive and produce the best possible results.


A walled garden is a controlled environment that is used for growing plants. These gardens can be found all over the world, and they offer many benefits to those who use them. If you are looking for a way to improve your gardening or farming results, then consider building a walled garden of your own.
