Bangladesh, being an active floodplain and owing to its diverse hydrological nature, is home to an astonishing diversity of aquatic and wetland-associated plant species. The centrally located Water Garden at the Climate Technology Park celebrates this rich floral diversity by embodying a collection of native and naturalized plants; accordingly distributed from open water up to the lake bank. This diverse assemblage of water-loving plants comes in a different size, shape, and colour which presents eye-soothing vista to the visitors in plain view, and all year round. But the garden also serves other important ecological functions at the same time – purifying water through the process of Phytoremediation, providing shelter to fish, amphibians, turtles-terrapins, and other aquatic lives, reducing water-loss from evapotranspiration just being few of the examples. It would also function as an arboretum for conserving rare and endangered wetland-associated plants of the country. The visitors would be able to encircle and enjoy the entire Water Garden via a continuous and elevated boardwalk equipped with periodic pavilions and information boards to introduce visitors with plant species and ecological functions of the garden.
