The Botanical Garden is a part of the National Biodiversity Centre and will focus on growing plants from Bhutan. The aim is to showcase examples of the country’s beautiful flora and to encourage the conservation of biodiversity. The rock garden is a unique blend of eastern and western horticultural styles. The medicinal plants area is also full of interest. The orchids in the orchidarium and tropical plants in the glass houses are interesting throughout the year. Some of the shrubs and flowerbeds have more seasonal interest.
