Ornamentals for greening

Industrialisation, urbanisation and population increase are gradually wiping out green from our living environment. As we continue our quick and ungraceful lunge towards cities, providing an optimal green space on planet earth has become a priority topic. Due to increased footprints of architecture in urban and suburb areas, land for landscaping has become scarce. In order to synchronize greenery with buildings, trendy technologies like rooftop gardening, vertical gardening and green walls can be used, in which ornamentals provide a seamless flow of greenery from the ground plane upwards. Ornamentals not only add to aesthetic value but also to the sustainable environment by acting as pollution barriers while maintaining bio-diversity. Plants that specifically reduce pollution from various sources have been identified and classed. Studies on the Air Pollution Tolerance Index (APTI) of many plants have contributed much to our knowledge in this sector. Proper utilisation of these plants would add life and visual quality to our environment, besides aiding in bringing mental and physical health back to man. A beautiful city with charming green surroundings would surely be the aspiration of all. Unless we seriously resort to a planned approach to place the green back, living on this planet would become very hard and expensive. Restoration of the ecosystem through ecological engineering, i.e., designing sustainable ecosystems that integrate human society with its natural environment, has thus become the need of the hour.
