On 8 July 1923, the Botanical Garden was officially opened with the laying of the foundation stone for the construction of the conservatory by President Aleksandras Stulginskis.
In 1923-1925, the Botanical Garden built its first greenhouses, the conservatory, which consisted of four compartments with a constant temperature and a pool for tropical plants. 1,770 different species of plants grew here. In the first year of its operation, the Botanical Garden was visited by five thousand visitors, and over the years it has become not only an educational base for biology, medicine and pharmacy students, but also an important centre of botanical science.
Nowadays, the VMU Botanical Garden's conservatory is the largest in Lithuania (1,093 sq. m. of floor space), and it has over 1,000 species of plants (1300 collection numbers). Separate sections display plants from cool tropics, warm tropics, rainforests, tropical forests, tropical tropics, humid tropics, deserts and semi-deserts.
