Research Facilities Greenhouse

Wilbur V. Harlan Greenhouse




Located on the top floor of Science and Engineering Hall, the 1,225-square-foot greenhouse opened in 2017. The rooftop facility is home to plants that support research on insects, climate change, genetic diversity and other active projects. Visitors can take a walk through time at the green facility to understand how plants have evolved over millions of years, and students are invited to study on the terrace, visit during open hours or apply for positions caring for the plants.
