Called the "Jungle Room" by many visitors, the Palm House is high in humidity and frequently watered. It houses a collection of plants from tropical regions of the world. Many of the plants, or their products, may be familiar. Coffee (Coffea arabica), banana (Musa x paradisiaca), and cacao (Theobroma cacao), are a few such. Some may not recognize our rubber (Hevea brasiliensis) and cinnamon (Cinnamomum zeylanicum) plants at first glance. In addition to these, an especially old specimen is the prickly cycad (Encephalartos altensteinii). It is a cycad with fernlike leaves and pinelike cones, and was planted as early as 1896, coming from the Durfee Conservatory at the University of Massachusetts.
