Abstract :
Urbanization has created a negative impact on the environment by increasing concrete areas and reducing the green cover to satisfy the rising population demands. Due to this the environment and its ecosystem has been affected to a great extent by the rising urban air temperature. This reason serves as a foundation for the development of a vertical greening system. VGS is a technique for growing plants on the vertical surface of buildings. This is an effective method to bring back the lost urban greenery and its benefits, as the horizontal green cover is replaced with buildings. The VGS not only expands the amount of greenery in cities but also serves other purposes including improving air quality, reducing heat islands, buffering the sound and heat, reducing energy consumption, increasing the urban aesthetic value, and enhancing human psychology. However, the development of VGS is being hindered due to its maintenance challenges. This study was conducted to highlight the maintenance challenges associated with the VGS and determine the advantages of using native plants in vertical gardens to reduce the maintenance challenges associated with it. In this context, a literature review was done on native plants and their advantages to the environment, benefits of using native plants on VGS, threats to native plants, and selection criteria of plants for VGS were examined. As a result of the study, it has been revealed that using native plants on VGS have an important place in urban areas especially for bringing back lost greenery and its benefits along with reducing the maintenance issue associated with VGS.
