These vines grow in the College of Business at University of South Florida, where I work. There's not much writing on the history of the building from what I searched for on Google. It might have been built under a different name. But from what I read on the USF website these fallout shelters were created in 1963 for the Cuban Missile Crisis. Students refer to this building as the bomb shelter or the bunker. It feels like another world when I walk the hallways.
