Amos Eno Greenhouse


In 1986 the College dedicated its newly built greenhouse in memory of Amos Eno, a former trustee of College of the Atlantic. Funds for the construction of the greenhouse were donated by Amos' wife Alice Eno, who became a trustee herself after his death. Alice was a very active supporter of the College; the Biological Research Station on Great Duck Island is named after her in recognition of her devotion to science and her love of the students of COA.


Like many COA facilities, the greenhouse is open to the public, but its primary purpose is to support classes in all of the Colleges's resource areas. Some of these classes include: 4D design, Environmental Chemistry, Gardens and Greenhouses, Environmental Physiology, Agroecology, and Edible Botany.

Many students chose to do class projects and independent research in the greenhouse. In the past, these projects have included photography, installation art, measurements of air quality, architectural plans, and hydroponic research. The greenhouse has two banks of growing lights for controlled experiments, and additional research space is available in a climate-contolled growth chamber in the basement of Turrets.

The greenhouse also serves as seasonal storage for many of COA's garden plants that are not winter-hardy.


The Amos Eno Greenhouse is run entirely by work study students under the supervision of Dr. Nishanta Rajakaruna, one of the College’s botany professors. The greenhouse is managed using organic gardening practices, and all organic waste is composted into the community garden compost pile. The greenhouse holds an annual plant sale on Earth Day to raise money for horticultural supplies.

The current work-study staff comprises: Becca Haydu (student manager), Rose Dawson, Elaina Burress, Emily Michaud, Gaia Lopez Barrera, Jenna Farineau, Josie Trople, and Katie Powell.


The Amos Eno Greenhouse holds a variety of plant specimens, with large collections of xeric plants (plants like cacti and succulents that can tolerate very low moisture) and tropical plants (such as bromeliads and orchids).
