Many plants that are not adapted to Stellenbosch's climate are housed in one of the Botanical Garden's four glasshouses. The tropical glasshouse and the two arid glasshouses are open to the public while the second tropical glasshouse is only open to the public on special occasions. Some of the orchids and other plants are regularly put on display in the tropical glasshouse.
Keys to the glasshouses can be signed out at the Shop from 8:00 to 16:30 daily.
