Colgate University's greenhouse contains approximately 1,000 plants used to demonstrate diversity, facilitate teaching, and provide color and visual interest throughout the year. The collection includes ferns, orchids, cactus, succulents, flowering vines, and more. This state-of-the-art facility in the Ho Interdisciplinary Science Center is approximately 3,000 square feet. The greenhouse contains six separate plant zones: the Tropical House, two Temperate Houses, and three Research Houses actively used by the Biology Department's faculty and students. An outreach program brings area school and other groups to visit, learn, and enjoy the greenhouse.
