A "Green Wall" is a vertical garden that consists of plants growing on a wall or a structure designed to support vegetation. These walls can be found in both indoor and outdoor settings and are often used to enhance aesthetics, improve air quality, and provide insulation. They can be made from various materials and may include a variety of plant species, such as ferns, succulents, and flowering plants. Green walls are beneficial for urban environments, as they help reduce heat, absorb carbon dioxide, and promote biodiversity. They can also contribute to noise reduction and provide a habitat for wildlife. Many cities are incorporating green walls into their architecture to create more sustainable and livable spaces, aligning with the principles of sustainable design and urban greening.
