The Botanical Garden of St. Gallen is located on Stephanshornstrasse 4 in the suburb of Neudorf in St. Gallen, and the garden displays 8000 species of plants collected from different regions around the world. The plants are distributed in the garden to the outdoor gardens and to the greenhouses. European plants are placed in the outdoor gardens because they can withstand cold weather, and tropical plants are placed in greenhouses because they need high heat. This botanical garden is considered a historical garden, as it was established in the year 1878, and it was initially a medium-sized garden with an area of 6000 square meters, but it expanded through the ages and became a very huge garden.
