The University's Botanical Gardens
The University’s Botanical Garden, started by Ulisse Aldovrandi, is one of the oldest in the world. It's also the second-largest park in the city centre, with a collection of mostly Mediterranean flora, rock and herb gardens and ponds, along with such exotica as a fully grown sequoia, and greenhouses for cacti and insectivorous plants.
There's also a Botanical Museum and a Herbarium; the latter houses over 100,000 dried plants, although this is open, by appointment, only to students and researchers with documents proving their studies.
