The National Botanical Garden is the largest plant conservation center in Bangladesh, with an area of around 84 hectares (210 acres). It is located at Mirpur in Dhaka, beside the Dhaka Zoo. It was established in 1961.  It is one of the greatest botanical garden of Bangladesh a knowledge center for nature lovers and botanists and a tourist destination. Here is a scientific collection of approximately 100,000 preserved specimens of plants. This is a very beautiful place for nature lovers.  I spend one day 2 month back. It is treasure in the city both for people seeking quiet green spaces and for all levels of botanies. 

The Sundari is one tree you will see in the garden. It commonly grows in mangroves, through it is a fresh water loving tree. The Sal tree is another tall and beautiful tree in the garden. It has broad leaves which in many places in South Asia, are shed in the dry season of late winter-early spring. I also see some magnolia flower. In this green ground have various known and unknown flowers and fruits tree.

There are clumps of towering bamboo in the garden as well and a cultivated section which roses, marigolds, salvia, dahlias and other enormous flowers can be found in the season. Best time to visit in winter. But any time of year the garden has its own unique charms.
