Plants are important constituents of the biota on this planet and greatly influence the quality of global environment. Today human survival is threatened due to the destruction of plant diversity because we can live on this planet only as long as there are plants. Botanic Gardens comprising arboretum, herbal garden, conservatories, green houses, experimental/display plots, aquatic bodies conserving incredibly diverse plant resources from various climatic regimes offer immense opportunities to the school children, college students, researchers as well as the general public to learn about the nature intricately. Visits of students, researchers, progressive farmers and the entrepreneurs   are frequently organized in the botanic garden. Summer training courses for the school children are also organized from time to time. Thus the garden is dedicated to environmental education and the conservation of plant diversity.


Authentic plant material of a wide variety of indigenous, exotic and ornamental plant species is propagated for sale to inculcate the bio-aesthetic sense among the general public and for making the herbarium specimens for students and research scholars from various colleges, universities and institutions. 


Botanic Garden renders technical advice on landscaping and ornamental horticulture, for improving the environment, to individuals, private and public sectors and  Government Organizations. Short education-cum-training programmes are conducted on cultivation of ornamentals, landscaping, garden layouts, bonsai and latest techniques in horticultural practices. Such programmes are generally sponsored by SIDBI and National Horticulture Mission for the horticulture officers, rural unemployed youths and the progressive farmers.


The Institute organizes two Annual Flower Shows viz: Chrysanthemum & Coleus Show in December and Rose & Gladiolus Show during January every year. These shows are of international standard displaying R&D work on ornamental horticulture for promoting interest among the garden lovers, progressive farmers, connoisseurs and the general public towards the cultivation or ornamental plants for improving their environmental surroundings.


NBRI Botanic Garden has been recognized as the Centre of Excellence by the   Ministry of Environment & Forests, Government of India, New Delhi. Under this programme  as well as under the CSIR's Supra Institutional project the following new creations have been proposed.
